release: version-less GUI installer aliases for stable download links

tauri-action names the installers with the version, which would break any
fixed download URL on the next release. Add a workflow step that uploads
version-less aliases (TutaBridge-macOS.dmg, TutaBridge-Windows-setup.exe,
TutaBridge-Linux.AppImage/.deb/.rpm) next to them, and point the README
download links at releases/latest/download of those stable names so they
follow every future release automatically. The CLI assets were already
version-less. The current rc.1 release was backfilled with the aliases.
