textproc/hs-megaparsec: update to megaparsec-9.7.0

## Megaparsec 9.7.0

* Implemented correct handling of wide Unicode characters in error messages.
  To that end, a new module `Text.Megaparsec.Unicode` was introduced. [Issue
  370](https://github.com/mrkkrp/megaparsec/issues/370).
* Inlined `Applicative` operators `(<*)` and `(*>)`. [PR
  566](https://github.com/mrkkrp/megaparsec/pull/566).
* `many` and `some` of the `Alternative` instance of `ParsecT` are now more
  efficient, since they use the monadic implementations under the hood.
  [Issue 567](https://github.com/mrkkrp/megaparsec/issues/567).
* Added `Text.Megaparsec.Error.errorBundlePrettyForGhcPreProcessors`. [PR
  573](https://github.com/mrkkrp/megaparsec/pull/573).
