[Metadata] Android desc = Steam desc (#4370)

Features:
- Kept the first 2 sentences intact. This means that roughly same text is displayed before clicking 'Read more'. 'Features include:' has been dropped for 'Gameplay Features', for Steam similarity.
- Steam-like formatting. I noticed that <h2> doesn't seem to do anything. Despite that, I've seen Gameloft using it. For something bigger, I'd recommend <big>.
- Updated blocks count. There's over 130 blocks. I triple checked.
- The old description still had 4 unique bosses. RIP.
- Steam Workshop & achievements and Android don't mix up.
- Checked against the character limit. It has less than 4000.
- Only cat-approved text.
