appstream: add 1.2.2 release

    from now on the archived sources will not be integrated in the AppStream releases notes. Instead, it will be replaced by the AppImage.

    They will be still available on the release page on github linked in the AppStream release. But the archive will only be created when pressing the release button on Github and thus its sha256 sum can not be part of the release itself.
