Fix and features:
- /!\ Last build before drop Ubuntu 20.04 LTS support
- Fix AppImage build (.desktop fail)
- Use matrix to build on GitHub Actions
- Fix GLib version issues with old builds thanks to new GitHub Actions PPA publishing
NOTE: I'm now publishing GitHub Actions builds in every release, all previous self compiled binaries are now removed. Both deb file and AppImage files are from the oldest supported Ubuntu version (currently focal).
Full Changelog: v1.3.2...v1.3.3
