style: apply prettier to ios-prebuild scripts and docs

`yarn format-check` (prettier) was failing CI on PR #57285. Run prettier on the
ios-prebuild headers scripts (headers-compose.js, headers-inventory.js),
replace-rncore-version.js, and __docs__/README.md so format-check passes. No
logic changes.
