appdata: Fix project license
The <project_license>
element is intended to state the license of the
project as a whole. The SPDX and
term means that the overall license
is the more restrictive union of both given licenses. That means that
the SPDX expression GPL-3.0+ and CC-BY-SA-3.0
is not FOSS.
This was causing Hitori to be shown as proprietary software in gnome-software.
See https://github.com/ximion/appstream/issues/312
Fix that by only giving the license of the code as the
<project_license>
, ignoring the license of the help manual.
