Add GitHub Action for building and publishing Docker images

• Add a GitHub Action for manual triggering to build Docker images from
  specified Git tags.
  • The workflow checks out the repository, validates the tag, builds images
    using a specified script, and pushes them to the GitHub Container Registry.
    Verification steps confirm successful image creation and include metadata
    annotations.
• Upgrade GitHub Actions dependencies:
  • actions/upload-artifact from v3 to v4. - actions/setup-java from v3 to v4.
  • Replaced gradle/gradle-build-action@v2 with gradle/actions/setup-gradle@v3.
  • Upgraded gradle/wrapper-validation-action@v1 to
    gradle/actions/wrapper-validation@v3.
• Upload unit test artifacts for each JDK in a separate file.
