Update node.js version to 20; update CI dependencies to remove warnings

[pzhlkj6612]

This PR completes #219 and fixes #220 .

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

CI shows many notes about node16, I think It's from https://github.com/jurplel/install-qt-action/blob/master/action/action.yml#L79

@jurplel Any plans to merge this in to v3 branch & release 3.3.1?

[jurplel]

Will do, there are some test failures on the v3 branch for some reason preventing immediate release

It looks like the failure is because the installed tools are not in the path in some conditions. Compare the outputs of stage "Test installed tools" for the workflow case "test (ubuntu-22.04, false, true, true, cached)": successful master:
