Fix jbang-example.java to use actual version instead of Maven placeholder

Replace ${project.version} with a real version number (0.2.2-java.1) in
jbang-example.java since this file is not Maven-filtered. Also add a
fallback sed pattern in the release workflow to handle the placeholder
during the transition.
