CI is not operational

[mandreux-owkin]

Currently, all CI jobs fail.

• #283 proves that the current setup cannot be installed in the CI, regardless of any modification.
• #280 proves that bumping the version of setuptools does not solve the issue either

So far, I have not been able to reproduce the issue locally with python 3.8, 3.9 or 3.10: all installations are fine locally (macOS + anaconda env + pip install -e ."[all_extra]", following what is currently in the CI).
