I bumped all the dependency versions to avoid issues, so there is a build
dependency chain to follow. But I don't know if this will negatively impact
package building if they are all uploaded at once.

The dep chains are as follows:
cura-engine -> libarcus-dev -> libarcus3
cura -> uranium-tools, python3-uranium -> python3-arcus -> libarcus3

The rest are only runtime dependencies.

Hmm... I don't think UltiMaker changed that.
I can ask them about it, but it looks like we need to patch this ourselves.
It would be good to refer them to an official policy instead of a personal
opinion, to give it more weight.

Since changing the logic would require changing the text as well, we're going
to need translations. Do you know if there is someone in the Debian project I
could ask about that?
