Wow, thanks for all your translations! 🤗

However, it is very difficult to review such a large PR. Would you mind breaking it up into smaller separate PRs? Also, keep in mind you'll need to find someone who can read Urdu to review your translated content.

I'll split the PR into smaller ones, as for the Urdu review I’ll coordinate with someone who can verify the translations let me know if you have any specific reviewer in mind or if I should arrange one 🤗
