Update GitHub actions checkout, cache and upload-artifact from v3 to v4

This fixes several CI warnings like this one:

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