Provide metainfo for Linux AppImage releases

[ProjectSynchro]

Is your feature request related to a problem? Please describe.
Small issue that really has no usability problems, but when integrating the wootility appimage with appimagelauncher:

The wootility logo and name don't seem to be properly included in the metadata for this appimage.

Describe the solution you'd like
Include metainfo for the Wootility in the appimage (located in AppDir/usr/share/metainfo)

Describe alternatives or workarounds you've considered
Manually creating a desktop file with references to a logo and the correct name/metadata

Additional context
Without knowing how things are built, (using linuxdeploy or something native to electron) you may need to specify the location manually for including the metainfo.
