Updates Prettier to v3.

This also means the minimum version of it as a peer dependency also gets bumped to the latest one. Maybe the peer dependency requirement should be changed to ^3?

I reverted the updated trailingCommas setting back to the v2 value to minimize the amount of formatting changes as recommended by @bluwy, but if @Andarist agrees I can revert to the default v3 config and re-format the files according to that.
(Personally I would also set the line-width to 90-100 as well, for better readability)

LGTM. I'm for the default trailing comma setting too, though given we still need to merge main into next for time to time, maybe we should hold back for now until next is nearly ready for stable.

Their API is largely compatible between v2 and v3. We are using getPrettierInstance helper to resolve a local installation first and that, to the best of my knowledge, is compatible with both versions. So this change only changes what gets loaded by default if we can't find an already installed Prettier.

after merging this i would recommend adding a .git-blame-ignore-revs file to exclude the formatting commit's changes from git and github's blames
