Installation of snaps on fedora-34

Following instructions sometimes the snaps e.g. Bitwarden start up in an app-VM sometimes they do not.

If they do not start up, no message is issued.

If they start up and the Template: fedora-34 is openend, then snap list reports no snaps are installed - in contrast to the just opened one.

Update: @ng0177 ran into issues with installing snaps in fedora-based qubes. Discussion followed in.
