Simplify maven build workflow and update actions

[HannesWell]

Use the maven-caching integrated into the setup-java action to replace the explicit usage of actions/cache: https://github.com/actions/setup-java/?tab=readme-ov-file#caching-maven-dependencies

Use the https://github.com/coactions/setup-xvfb instead of installing xvfb manually.

Run Maven in --batch-mode to suppress transfer print-out.
