book: mark the Persian translation as complete! (#2091)

## Changes

- Moves the Persian translation of the ProGit book from the "translation
started" section to the "full translation available one".

## Context

🎉

Huge shout-out to @YasinDehfuli for the enormous effort to overhaul and
complete the translation! For full details (and a _glimpse_ on the
size), see progit/progit2-fa#19.
