[PEP-625] Update setuptools to canonicalize filename. (#225)

This patch updates `setuptools` to address PEP 625
(https://peps.python.org/pep-0625/). As a part of this patch, we have to update
a number of GH dependencies that have been deprecated:

  - Artifact actions v3 will be closing down by January 30, 2025.
  - Starting February 1st, 2025, we will begin the process of closing down
    v1-v2 of actions/cache
  - The Ubuntu 20.04 runner image will be fully unsupported by April 1, 2025.
