refactor: simplify gitattributes using override pattern for English locales

Instead of explicitly listing each non-English locale, we now:
1. Mark all locale directories as linguist-generated
2. Override English directories to be linguist-generated=false

This approach is cleaner, more maintainable, and automatically handles new locales.
