Summary:
Fixes missing/incorrect devDependencies in a newly built app. The previous set did not pull in prettier, causing linting to fail. There was a peerDependency warning on yarn install. We also saw a separate lint warning at runtime specific to TS 4.9 being pulled in now, so we constrain in that version a bit.
Prettier and preset-env versions match the constraints and lockfiles of other RN packages.
## Changelog
[General] [Fixed] - Fixup template devDependencies
Pull Request resolved: https://github.com/facebook/react-native/pull/35372
Test Plan:
Created a new app targeting 0.71 via `react-native init`.
1. `yarn install --force` no longer shows warnings
2. `prettier` is installed, `yarn lint` no longer fails, and shows no warnings or errors
3. ~Tentatively a test step to add tests against linting in new app, but last time doing that in CircleCI led to timeouts with no output that I didn't have time to debug, so maybe that's fixed now? �♀️.~ (edit: still hangs)
