Downgrade prettier to 3.1.0 to help changesets format changelog.md

[siddharthkp]

Hello!

I went into a silly rabbit hole of CI and come back with this:

• Noticed that CI is failing in Release tracking (37.3.0) #5234, because npm run format found unrelated changes in CHANGELOG.md
• This happens because changesets can no longer find our prettierConfig from package.json
• This started happening last week with the upgrade to prettier from 3.0.0 to 3.3.3 chore(deps-dev): bump prettier from 3.0.3 to 3.3.3 #5180
• This was introduced in prettier 3.1.1 Implement our own config explorer prettier/prettier#15663
• Related doc change: https://github.com/prettier/prettier/pull/15910/files
• Looks like changsets has not updated their code to match this change.
• Downgrading prettier to 3.1.0, so that we don't have to deal with this for now. Hopefully, this will be fixed in changesets soon. Otherwise, we can look into debugging and submitted a PR

Could we also exclude CHANGELOG.md from prettier in .prettierignore to avoid downgrading or would that also cause issues? 👀

That wouldn't stop changesets from running prettier on it, but it will stop our format CI job complaining about it.

changesets would not format it with our prettier config, which is only slightly annoying. I don't mind.
