AppImages support a X-AppImage-Version field in the .desktop file to embed version information on the appimage, this is used by desktop integration solutions such as AppImageLauncher in which it adds the version information on to the name of the app in the application list. e.g "AppName (1.0.0)" where the version is picked up from the X-AppImage-Version property.
I've seen all major appimages come with this property but not osu!, currently that desktop integration thing ends up making osu appear as "osu! (1)" since version information is missing.
You do not need to add this field into the .desktop file manually as the appimagetool seems to support adding this automatically on presence of the $VERSION variable as seen here
