[React Native - ios] The following Swift pods cannot yet be integrated as static libraries

* Firebase 관련 수정 후 pod install --repo-update 시에 발생

 

# 현상

[!] The following Swift pods cannot yet be integrated as static libraries: The Swift pod `FirebaseCoreInternal` depends upon `GoogleUtilities`, which does not define modules. To opt into those targets generating module maps (which is necessary to import them from Swift when building as static libraries), you may set `use_modular_headers!` globally in your Podfile, or specify `:modular_headers => true` for particular dependencies. The Swift pod `FirebaseStorage` depends upon `FirebaseStorageInternal`, `FirebaseAppCheckInterop`, `FirebaseAuthInterop`, `FirebaseCore`, and `FirebaseCoreExtension`, which do not define modules. To opt into those targets generating module maps (which is necessary to import them from Swift when building as static libraries), you may set `use_modular_headers!` globally in your Podfile, or specify `:modular_headers => true` for particular dependencies.
