Subject: [PATCH] fix(oxfmt/tailwindcss): Bundle `prettier/plugins/*` (#17782)

Fixes #17762

---

TL;DR: `experimentalTailwindcss` wasn't working in environments where `prettier` wasn't installed separately.

We had agreed in the review that it wasn't necessary, but it seems it actually was needed.
