situation is not super nice, but in general several problems exist,
- some files do not include any license, assumption is unless specified
explicitly they follow same license as the source package
(GPL-3.0-or-later).
- most files do not include the proper copyright statement, I have
specified KDE Localization team as copyright contact.
- license files do not follow SPDX headers, so we need to add them in
dep5.
I will start a thread in kde-core-devel / kde-i18n-doc mailing list
about licensing situation once 0.2 release is out.
Apparently having *.license files among asssets triggers build failures
from the Android tooling/androiddeployqt.
Move the licensing/copyright notices to .reuse/dep5 as a work-around.
