Added support for Urdu language

Fixes #2633

Changes:

I've added support for Urdu language to the p5.js web editor. This added feature will improve the accessibility of the editor, and make it more inclusive and easy-to-learn for the Urdu-speaking community.

As a native Urdu speaker, I've checked and verified that all the translations are correct, concise, and convey the intended meaning.

Thanks for working on this! I don't speak Urdu but the PR looks good so I'm going to go ahead and approve it.
