Summary:
This resolves issues where the node_modules structure is not hoisted (like with pnpm). Since the template does not directly depend on the cli, it doesn't exist in the pnpm node_modules root. Moving it to the rn scripts makes sure that the relative require starts in the correct directory for both hoisted and pnpm structures.
## Changelog
[iOS] [Fixed] - Fix cocoapods cli native_modules require for pnpm node_modules
Pull Request resolved: https://github.com/facebook/react-native/pull/34215
Test Plan:
1. react-native init
2. rm -rf node_modules
3. pnpm i
4. bundle install
5. bundle exec pod install --project-directory=ios
This should succeed. Without the patch, it will fail with
```
