[maurerle]

Currently each pipeline has warnings to it regarding the deprecation of node.js 16 actions like:

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

This PR updates the versions of the pipeline accordingly.
