    tag-manager: Use custom tag for starred items
    
    Currently we use nao:predefined-tag-favorite, which is used by other
    applications (example: gnome-photos) to tag favorite content. As such,
    favorite photos show up as starred files in Files.
    
    This is not what we currently want, because Favoriting has a different
    meaning and function than Starring.
    
    Instead, create our own custom tag <urn:gnome:nautilus:starred>
    and use that instead of nao:predefined-tag-favorite.
    
    Fixes https://gitlab.gnome.org/GNOME/nautilus/issues/277
    
    
    (cherry picked from commit 9e35fd628ae9c949c57cae86b9b40c83d4ccbd60)
