[new release] yojson and yojson-five (3.0.0)

CHANGES:

*2025-05-39*

### Changed

- Floats are now always output to JSON in a standard-conformant way or not at
  all (raising an exception). This makes the `std` variants of functions
  identical to the non-`std` variants and the `std` arguments have no effect.
  Users are encouraged to switch to the non-`std` affixed variants, the others
  will be deprecated in the future.  (ocaml-community/yojson#184, @Leonidas-from-XIV)
- Bumped the minimum required version of OCaml for the main package to 4.08
  since the CI dropped the support. This however allows removing the dependency
  on the `seq` library, so the depencency cone becomes slightly smaller. (ocaml-community/yojson#194,
  @Leonidas-from-XIV)

### Fixed

- Fixed handling of escape sequences in JSON5. Known escapes like \b will be
  properly unescaped and undefined escape sequences will unescape to the
  character itself as per spec (ocaml-community/yojson#187, @david-maison-TrustInSoft)
- Fixed tests failing on Windows due to disagreements with the length of an
  input channel and the text mode conversion (ocaml-community/yojson#192, @Leonidas-from-XIV)

### Removed

- Removed support for Tuple and Variant in JSON. It was a non-standard
  extension that was rarely used, so this simplifies the Yojson types and the
  parser more standard-conforming (ocaml-community/yojson#105, ocaml-community/yojson#158, ocaml-community/yojson#185 @Leonidas-from-XIV)
