    file: Ability to change file-owner in admin:/// backend
    
    Running nautilus as root is no longer recommended/supported.
    Priviledged operations like changing file owner, while
    running as non-root are supported by the admin backend.
    
    Closes: https://gitlab.gnome.org/GNOME/nautilus/-/issues/1534
