Comply with ruff lint so that hopefully CI will build packages again

Edit: seems like this is more complex than it seemed, there are also a bunch of errors from the type check, see: https://github.com/stisa/compas_slicer/actions/runs/25364385163/job/74371415800
I'll convert this to a draft for now until I have time to go through it

What type of change is this?

• Bug fix in a backwards-compatible manner.
