Subject: [PATCH] Upgrade formatting to Prettier 3.10.0 (#2226)

Summary:
X-link: https://github.com/react/react-native/pull/60005


Upgrade formatter dependencies and retained locks to Prettier 3.10.0, with the compatible CLI and source changes needed for a self-contained upgrade prefix. Preserve runtime behavior, Flow types and parser/style policy; exclude the retained Yjs bundle with `noformat` instead of reformatting its generated body.

Changelog: [Internal]
