Update actions workflow to use node 24 actions

[rhit-steineig]

• Our github actions runner for the "test" workflow shows this annotation:
  Node.js 20 actions are deprecated. The following actions are running on Node.js 20 and may not work as expected: actions/checkout@v4, actions/setup-node@v4, actions/upload-artifact@v4. Actions will be forced to run with Node.js 24 by default starting June 2nd, 2026. Please check if updated versions of these actions are available that support Node.js 24. To opt into Node.js 24 now, set the FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true environment variable on the runner or in your workflow file. Once Node.js 24 becomes the default, you can temporarily opt out by setting ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true. For more information see: https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/
• The solution may be as simple as replacing @v4 in actions/checkout@v4, actions/setup-node@v4, actions/upload-artifact@v4 with @v5 in .github/workflows/test.yml
• consider updating the release-ghcr-files.yml and docker-publish.yml workflows as well

Ideally the version of node the actions use should be the same as the one the system uses
