chore: update to Jest v29

[SimenB]

👋

I noticed you were on an old version when looking through the code, so I thought to update it.

Main changes are:

• Update RN, stop hoisting it and use own transformer
• Set default test env to jsdom (changed default in Jest 27)
• Map some @remix-run/* modules to their CJS counterpart
  • This is due to Jest supporting exports, and those modules always serving ESM when Jest provides browser and require conditions. See https://jestjs.io/docs/28.x/upgrading-to-jest28#packagejson-exports
  • This could probably be fixed by tweaking the exports in those modules, but I didn't look into it
• Update snapshots due to changed defaults: https://jestjs.io/docs/upgrading-to-jest29#snapshot-format

Hey team, any update on getting this merged? Jest 28+ doesn't appear to be compatible with Remix packages without addressing the package import issue mentioned above. Thanks!

I fixed the conflicts, but it looks like there's been enough updates since this PR to require more changes. Let me look into it...

@timdorr seems like snapshots are different since Jest 29 https://jestjs.io/blog/2022/08/25/jest-29 and need to be updated.

OK, now for the fun part: This was based on main, not the dev branch (which should be ahead code-wise and is where this should target). I got it fixed on main, so hopefully this is just resolving those conflicts. Fun! :S

Switching to #9895 because I can't push to this remote branch anymore. Not Simen's fault, just a GitHub thing.
