Added Persian/Farsi Translations

[mosnfar]

I added the Persian (Farsi) translation. The changes are:

• Added Persian (Farsi) markdowns.
• Reviewed and improved some translated texts for clarity.

P.S. Further refinements are needed for consistency and readability. Feedback and suggestions for improvement are welcome.
