devel/alex: Update to 3.4.0.0

Changes in 3.4.0.0 [Andreas Abel, 2023-06-20]
* New wrappers to lex strict Text: strict-text, posn-strict-text,
  monad-strict-text and monadUserState-strict-text (PR #240). These
  complement the existing wrappers for String and ByteString.
* Tested with GHC 7.0 - 9.6.2.

Changes in 3.3.0.0 [Andreas Abel, 2023-05-25]
* Add an Ord instance to AlexPosn (Issue #233). This breaks developments
  that define their own (orphan) instance Ord AlexPosn. If this is the
  derived stock instance, the fix is to delete the orphan instance and
  require build-tool-depends: alex:alex >= 3.3.0.0.
* Switch to Haskell PVP versioning with four digits.
* Tested with GHC 7.0 - 9.6.1.

Change in 3.2.7.4 [Andreas Abel, 2023-05-02]
* The user-supplied "epilogue" Haskell code is now put last in the
  generated file. This enables use of Template Haskell in the
  epilogue. (Issue #125.)
* Tested with GHC 7.0 - 9.6.1.

Change in 3.2.7.3 [Andreas Abel, 2023-04-14]
* Amend last change (3.2.7.2) so that Alex-generated code does not need
  LANGUAGE PatternGuards.
* Tested with GHC 7.0 - 9.6.1.

Change in 3.2.7.2 [Andreas Abel, 2023-04-03]
* Fix bug with out-of-bound access to alex_check array. (Surfaced with
  GHC's JS backend, fixed by Sylvain Henry in PR #223.)
* Tested with GHC 7.0 - 9.6.1.
