Thank you Ingo and Albert,
so same licence as original file.

Regarding the copyright, as the files will be added via nightly
scripts, it will be difficult to automatically update the .reuse/dep5
file, is it possible to have a:
Copyright: 2023 KDE translators <kde at kde.org>.
Comment: See the corresponding po files in the po/ folder for the
correct copyright attribution

I would prefer to avoid updating the file automatically or checking
everyday if it needs to be updated.

Cheers,
Johnny
