Subject: [PATCH] Enable useFabricInterop by default for internal apps (#50295)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/50295

Enabling `useFabricInterop` by default for internal apps since before D71582553 iOS wasn't using useFabricInterop in it's codebase and old architecture with Interop enabled is harmless.

This is to keep the current behaviour consistent.

Changelog: [Internal]
