Language request: Punjabi (Shahmukhi)

Hey Readlang team,

Your support for Punjabi has been great. It works pretty well and I love seeing the improvement from when I last tried out Readlang. My feedback request is that you also add Punjabi (Shahmukhi).

Punjabi is split into two scripts: Gurmukhi (which is the one currently supported on Readlang, and the one used in India) and Shahmukhi which is used in Pakistan. Shahmukhi uses a modified Perso-Arabic script. I was thinking that it shouldn’t be too hard, as you already support R-to-L languages like Urdu.

The ISO code is pnb. Here’s a link to the PNB Wikipedia here, and a native academic dictionary here.

Thank you!
