[gparted/12-appstream-metadata-needs-valid-license] Update GParted appdata file (#12)

[Mike Fleetwood <mfleetwo src gnome org>]

commit 8ebe384f699830f817b0fa2eaab47cd51285b660

    Update GParted appdata file (#12)
    
    Update appdata file to be inline with the current AppStream
    specification [1].  Start by running:
        appstream-util upgrade gparted.appdata.xml.in
    and then editing the appdata as wanted.  Ensure that the file passes
    validation:
        appstream-util validate-relax --nonet gparted.appdata.xml.in
    
    When Richard Hughes added the appdata file he licensed it under the
    GFDL but assigned the copyright to Curtis Gedak [3].  Now change the
    license to CC0-1.0 [4] as that is what most appdata files are licensed
    under [5][6].  Curtis Gedak agrees to this by reviewing this change and
    being the committer of this commit.
