Re-enable iOS integration tests (#37571)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/37571

During the RC.0 of 0.72, we disabled the iOS integration tests because they were not working with Metro and the new Monorepo setup.

This change tries to re-enable them so we can be more protected in CI
