[3dprinter-general] Cura Appstream data patch

[Gregor Riepl]

Hi,

I submitted a patch to fix the Appstream warnings we were getting for
Cura: https://github.com/Ultimaker/Cura/pull/9229
Full discussion is here: https://github.com/Ultimaker/Cura/issues/9217
Debian Appstream report:
https://appstream.debian.org/sid/main/issues/cura.html

It was happily merged upstream, but we probably won't get the next Cura
release into bullseye.

Would it make sense to add this to the Debian 4.8 release?

Regards,
Greg
