Solve formatting issues (stylish-haskell, pre-commit CI)

[andys8]

Because of the failing pre-commit hook #3170 a bunch of files are checked in, but not formatted as expected.

Note: The commit hook will still fail because of the first reason (stylish haskell parse errors, #3170)

Have you checked #3131 and #3145 out? Just in case the work is duplicated.

@kokobd I haven't. So thanks for the hint.

• Reformat repository to clean up failing CI step #3131 appears to be closed. Is the work gone or in a different PR?
• Only run the pre-commit hook on changed files #3145 seems to address running the hook only on changed files. Would not be relevant.

In case this PR is duplicated, I'm happy to close it ;)

The closed PR I eventually found a file that needed a complete overhaul to remove the stylish Haskell error.

#3145 is intended to run just changes files to hopefully minimize the amount of formatting failures on CI. I have an approval but am going to try to remove the dependency on another action when I get some spare time.

e134351 addresses some of the parse issues, but not all. This PR could be overlapping / duplicating the work done in #3131. While this doesn't solve all issues, solving some of them and making sure the repository won't grow more issues with new PRs would be an improvement. So this PR or part of the work of #3131 could help.

I don't see any downsides to merging this. Thanks!
