Log Message:
gleam: update to version 0.30.4

Changelog:

## v0.30.4 - 2023-07-26

- External implementations are always referenced directly in generated code, to
  avoid the overhead of an extra function call.
- Fixed a bug where the compiler could infer incorrect generic type parameters
  when analysing a module without type annotations with self recursive
  functions that reference themselves multiple times.

## v0.30.3 - 2023-07-23

- Fixed a bug where JavaScript module path such as `node:fs` would be rejected.
- New Gleam projects are created with `gleam_stdlib` v0.30, Erlang OTP v26.0.2,
  Elixir v1.15.4, actions/checkout v3.5.1, and erlef/setup-beam v1.16.0.

## v0.30.2 - 2023-07-20

- Fixed a bug where the compiler could infer incorrect generic type parameters
  when analysing a module without type annotations with self recursive
  functions.
- Fixed a bug where the formatter would incorrectly format external functions
  by breaking the return annotation instead of the function arguments.

## v0.30.1 - 2023-07-13

- Fixed a bug where the language server could fail to import path dependencies
  in monorepos.

## v0.30.0 - 2023-07-12

- A warning is now emitted for the deprecated external fn syntax.

## v0.30.0-rc4 - 2023-07-10

- An error is now emitted for invalid JavaScript external implementations.
- Fixed a bug where Erlang external implementations could generate invalid code.

## v0.30.0-rc3 - 2023-07-05

- Fixed a bug where `gleam fix` would fail to parse command line flags.

## v0.30.0-rc2 - 2023-07-03

- Fixed a bug where `gleam fix` would merge external functions of the same name
  but incompatible types.
- Fixed a bug where external function arguments would incorrectly be marked as
  unused.

## v0.30.0-rc1 - 2023-06-29

- The new `@target(erlang)` and `@target(javascript)` attribute syntax has been
  added for conditional compilation. The existing `if` conditional compilation
  syntax has been deprecated. Run `gleam fix` to update your code.
- The new `type TypeName` syntax syntax replaces the `external type TypeName`
  syntax. The existing external type syntax has been deprecated. Run `gleam format`
  to update your code.
- Adding a new dependency now unlocks the target package. This helps avoid
  failing to find a suitable version for the package due to already being
  locked.
- A custom message can now be specified for `panic` with `panic as "..."`.
- The syntax for specifying a custom message for `todo` is now `todo as \ 
"..."`.
- The Erlang error raised by `let assert` is now tagged `let_assert`.
- Types named `Dynamic` are now called `dynamic_` in Erlang to avoid a clash
  with the new Erlang `dynamic` type introduced in OTP26.
- Dependencies can now be loaded from paths using the
  `packagename = { path = "..." }` syntax in `gleam.toml`.
- The `javascript.deno.unstable` field in `gleam.toml` can now be used to
  enable Deno's unstable APIs when targeting JavaScript.
- Blockquotes are now styled in rendered HTML documentation.
- The `gleam` property can be set in `gleam.toml` can be set to a version
  requirement to specify the version of Gleam required to build the project.
- Type aliases can now refer to type aliases defined later in the same module.
- Fixed a bug where unapplied record constructors in constant expressions would
  generate invalid Erlang.
- Fixed a bug where the prescedence of `<>` and `|>` would clash.
- Fixed a bug where `gleam docs build` would print an incorrect path upon
  completion.
- Warnings from dependency packages are no longer surfaced in the language
  server.
- A warning is now emitted when a Gleam file is found with an invalid name.
- A warning is now emitted when using `list.length` to check for the empty list,
  which is slow compared to checking for equality or pattern matching (#2180).
- The new `gleam remove <package_name>` can be used to remove dependencies
  from a Gleam project.
- Fixed a bug where the formatter could crash.
- Fixed a bug where invalid Erlang would be generated when piping into `panic`.
- The `gleam docs build` command gains the `--open` flag to open the docs after
  they are generated (#2188).
- Fixed a bug where type annotations for constants could not be written with
  type annotations.
- Updated font loading in generated HTML documentation to fix an issue with
  fonts not loading properly in some browsers (#2209).

## v0.29.0 - 2023-05-23

- New projects now require `gleam_stdlib` v0.29.

## v0.29.0-rc2 - 2023-05-22

- The `gleam lsp` command is no longer hidden from the help output.
- Fixed a bug where some language server clients would show autocompletion
  suggestions too eagerly.

## v0.29.0-rc1 - 2023-05-16

- The language server will now provide autocomplete suggestions for types and
  values either imported or defined at the top level of the current module.
- Fixed a bug where record patterns using the spread operator (`..`) to discard
  unwanted arguments would not type check correctly when the record had no
  labelled fields.
- Add support for using sized binary segments in pattern matches when targeting
  JavaScript.
- A warning is now emitted for double unary negation on ints (`--`) and bools
  (`!!`) as this does nothing but return the original value.
- Previously the build tool would discard the entire build directory when \ 
dependencies
  were changed. Now it will only discard the build artefacts for removed
  dependencies.
- The errors emitted when a name is reused in a module have been made clearer.
- Fixed an incorrect URL in the error message for failing to parse a let binding
  with a type annotation.
- Fixed a bug where shadowing a prelude type name could result in incorrect
  errors in exhaustiveness checking.
- Fixed a bug where the language server would in some scenarios not remove an
  error diagnostic after it becomes outdated.
- Fixed a bug where the formatter would incorrectly format blocks with a comment
  before them that were the only argument to a function call.
- Fixed a bug where the language server would not reset the build directory when
  it was created by a different version of Gleam.
- New Gleam projects are created with `erlef/setup-beam@v1.15.4` in their GitHub
  actions CI configuration.
- Running a module now uses the dependency's target and runtime in its `gleam.toml`.
