Closes #41

  • New build arg JAVA_VERSION (17, 21, 25), default 17 keeps the existing
    images and tags
  • Java 21 and 25 images get a -jdk21 or -jdk25 tag suffix, Java 17 is
    also tagged -jdk17
  • Workflows build and test all three Java versions
  • pipeline.sh only uses the gha cache inside GitHub Actions, so it also
    runs locally

Not verified yet: JMX Prometheus agent 0.12.0 and WildFly on Java 25.

Very good. What are the next steps? Are you able and willing to push Docker images to Docker Hub?

The nightly build should start publishing snapshots.
Operaton 2.1.6 and 2.2.0 will be released on Oct 23th. I expect that the images will be published then.
