Hello @xNIGMAx, thanks for the contribution. Looks like you changed already existing Pashto language. When adding new language you should just add new file, not change the existing one.
Regarding Palestinian language, we don't have Palestinian language as a separate language, but we have Arabic. Is that somehow different from Palestinian language or not? Wikipedia article says that there are few languages spoken in Palestine.

Your changes may be related to the changes proposed in #108432.

Hey @rammba, yes issue #108432 is likely what happened due to the prettier extension, I will look into it.

As for the Palestinian language, it originates from levantine arabic that has many stiff, different punctuation and words. There are 2 main Palestinian arabic languages (dialectes that change many words), Palestinian Madani, and Falahi. And the one that I have translated was the Palestinian Madani.

I would say, that most Palestinians can read Readme.ar.md which represents the formal Arabic, but I added as a way for me to learn and contribute in something beneficial to people who may have hard time understanding the formal Arabic.

Great, thanks for the clarification @xNIGMAx.
Since @Roshanjossey, declined changes proposed in #108432, I think best idea is to see what is his opinion aboout this change.
