[quadrapassel/wip/wjt/appdata-project_license] appdata: Remove documentation license

    appdata: Remove documentation license
    
    The code in this project is covered by GPL-2.0+. The documentation is
    covered by CC-BY-SA-3.0. As outlined on the GNOME Software wiki,
    combining these two licenses with 'and' produces incorrect results, with
    GNOME Software considering the project as a whole to be non-free (since
    OSI does not consider CC-BY-SA-3.0 to be a free license for software).
    
    Instead, list only the code's license in the appdata. This is
    recommended by the appstream specification, and causes Software to
    correctly label this application as free software.
