Fix typo in language name (Panjabi -> Punjabi)

[DevRanbir]

Hello devs,
I Noticed a small typo in the supported languages list where "Punjabi" was spelled as "Panjabi". You can verify the standard English spelling here: https://en.wikipedia.org/wiki/Punjabi_language

This PR corrects the spelling to "Punjabi" (and "Western Punjabi") across the TSV, the markdown docs, and the Python language map so it renders correctly in the Gradio UI and API.

Thanks for the awesome project! Let me know if you need any changes.

Hi, I think both names exist. It’s also mentioned in the link you provided: Punjabi, sometimes spelled Panjabi.
