Scarab: äldre versioner att ladda ner

Bump version
This release has
- Skipping Scarab updates and showing their changelogs
- Better support for proton (controllers should work better)
- Markdown fixes
- Slightly improved dep handling
- Better handling of broken installs
- Updated avalonia
- --version cli flag
In the works is currently flatpak support, which I plan on getting onto flathub, as well as just some stability stuff I haven't gotten to
quite yet. Sorry for the wait. I'd like to ideally get some of that stuff done soon-ish, but I'm bad with timelines so no promises.
