[CI] Upgraded Actions

The Annotations section of the CI was full of deprecation warnings.

Node.js 16 actions were deprecated. Upgraded setup-python, checkout, and
upload-artifact to their most recent version. See:
https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/

v3 of upload-artifact was also deprecated. v4 claims to be 98% faster,
however, may come with some breaking changes. Pertaining to us,
artifacts cannot have the same name now and there is a limit of 500
artifacts. See:
https://github.blog/changelog/2024-04-16-deprecation-notice-v3-of-the-artifact-actions/

NOTE: Had to leave the nightly tests behind since the self-hosted
machine does not support node20. Need to upgrade the machine in order to
upgrade these actions.
