Show type alias name in union member errors (#55604)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/55604

When reporting added/removed union members of type TypeAliasTypeAnnotation, the error message showed the generic type kind "TypeAliasTypeAnnotation" instead of the actual alias name (e.g., "ObjectC"). This adds a case to getTypeAnnotationLabel to return the alias name for TypeAliasTypeAnnotation, producing clearer error messages like "Member ObjectC" instead of "Member TypeAliasTypeAnnotation".
