Summary:
While testing `use_frameworks! :linkage => :static`, I encountered nullability warnings that were previously suppressed because we always build with `-Werror`. I'm not sure why the suppressions no longer work, but they should just be fixed.
## Changelog
[IOS] [FIXED] - Fix nullability warnings
Pull Request resolved: https://github.com/facebook/react-native/pull/36247
Test Plan: iOS build should succeed.
