Migrate from prettier to oxfmt

[mstange]

Numbers from my machine:
yarn prettier-fix before: 6.5 seconds
yarn fmt after: 1.3 seconds

yarn lint-fix is still slow (9 seconds), I think that's bottlenecked on eslint.

Hi there—have you tried biome.js? I've been using it in my projects, and I think it's actually pretty good.

Thanks for taking care of this! I've added just one nit (comment update), otherwise lgtm 👍🏻

eslint-config-prettier essentially disables a bunch of formatting rules that might clash with the prettier formatting. I wonder if we need something for oxfmt too, but I think it's fine if it didn't clash already after the migration.

I haven't tried it, I have no opinion on which to prefer. In any case, it's not hard to switch.
