CI Github Actions deprecations

[ptheywood]

Node.js 16 actions are deprecated. Please update the following actions to use Node.js 20: actions/checkout@v3, actions/setup-python@v4. For more information see: https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/.

• [ ] Update CI actions to node js 20
• [ ] Update actions/upload-artifact and actions/download-artfact to v4 where required.

We also need to upgrade use of actions/upload-artifact and actions/download-artifact to v4 by 2024-11-30

Starting November 30, 2024, GitHub Actions customers will no longer be able to use v3 of actions/upload-artifact or actions/download-artifact. Customers should update workflows to begin using v4 of the artifact actions as soon as possible. While v4 of the artifact actions improves upload and download speeds by up to 98% and includes several new features, there are key differences from previous versions that may require updates to your workflows. Please see the documentation in the project repositories for guidance on how to migrate your workflows.

This is blocked by Node 20 actions not being compatible with Centos7 containers due to glibc requirements.

Hopefully this is resolved by github before 2024-11-30...

See #1200 for the failing implementation of this.
