bump kotlinter to 3.14 and ktlint action to 1.5.1

this replaces #83

the reformatting is done in a separate commit to make review easier, and enable us to revert it if we want to change code style options

the lint task now works, but there seems to be a different problem now. I tried updating gradle to 8.0.2, but that triggered a different problem. maybe the best thing is to bump all dependencies and then revisit this pr.

I can help with Gradle issues if you share the problem ;) But agree, bump deps first is probably better than solving and bundling more into one PR. Tip: you can remove the kotlinter integration from this PR and just merge the ktlint action, configuration and reformat as one unit. This moves things forward, and future kotlinter PR will be tiny.

you could do a separate pr that bumps gradle to 8.0.2

Now that #87 has been merged, will we be able to leave the kotlinter plugin enabled?

no, because it still fails. the fix seems to be in kotlin 1.8, and that needs api changes. So i would keep kotlinter disabled while we still support kotlin 1.7.
I made a new kotlin 1.8.2 pr to check that it will work with 1.8.2 here: #89

Thanks for this! I'm going to try and release a new version today so we can also get #89 merged and released as soon as possible.
