chore(about): update contributors, remove feature tagline, limit changelog to 3

- Add missing contributions: cucadmuh (PR #144, #167, #173, #174),
  kveld9 (PR #168), nisarg-78 (PR #115)
- Remove aboutFeatures tag line from all 8 locales (too dynamic to maintain)
- Changelog section now shows only the 3 most recent versions
