py-dot: updated to 3.0.4

3.0.4 (2025-01-05)

- Fixed capitalized keywords in labels being unquoted.

3.0.3 (2024-11-30)

- Fixed numeric quoting behavior.

3.0.2 (2024-09-25)

Added:
- All `to_string()` methods now accept an `indent` keyword argument, which can be
  either a number or a string. `indentation=4` will indent each level of the
  output with four spaces. `indentation="  "` will indent each level \ 
by that many
  spaces. Other whitespace is also valid, e.g. indent="\t" for tab indents.

Changed:
- Fixed quoting of identifiers with dots.
- Fixed quoting of leading-numeral strings (strings starting with a number).
- Fixed pickling/copying of Dot objects.
- Improved handling of temporary files. Temporary files will be cleaned up in
  all cases, even when exceptions are raised or things exit unexpectedly.
- From now on, the license files will be included in the distributed
  release as expected.

3.0.1 (2024-07-16)

This is a bugfix release to correct a critical error introduced in 3.0.0.

Changed:
- Fix quoting in `Edge.to_string()`.
