DevOps: Pin version of setuptools as it breaks dependencies (aiidat…

…eam#5782)

The last version `setuptools==65.6.0` that was released today, breaks a
number of packages, e.g., `numpy`, because it removed the `Log` resource
from the `distutils.log` module. We temporarily pin the version to
`setuptools==65.5.0` in the CI pipeline until a more permanent fix
upstream is released.
