    flatpak: Drop "(Development)" desktop file name prefix
    
    Since the introduction of the nightly icon in commit 91d519e47d8,
    there is no need to use a label to differentiate the stable and
    unstable/development instances of Boxes.
    
    Besides, the label ellipsizes badly in the Shell
