Improve Russian translation and fix description redundancy

[marioaltecci]

Updated the Russian metadata to fix a couple of issues:

• Eliminated redundancy: Removed the duplicate intro line that was appearing twice in Droid-ify (due to short and full descriptions merging).
• Improved formatting: Added <b> tags to the "Features" section to make it more readable and match the English source style.
• Better phrasing: Rewrote the main description to sound more natural while keeping the "Droid-ify is..." intro for better context.

Now the description flows logically without repeating the same sentence twice.
