Update PR CI to run on JDK 8, 17, 21, and 25

Modified .github/workflows/pr.yml to use a matrix strategy for testing across multiple JDK versions.
Ensured that artifact generation, static analysis, and reporting steps are executed only for the default JDK 8 build.
Retained legacy JDK 8 setup (with JavaFX) while using setup-java@v4 for newer JDKs.
