Remove obsolete "Wait for Maven Central" job

Since the "Publish to Maven Central" job now waits for the deployment to
reach "published" state, there's no longer a need to poll Maven Central
for the deployed artifacts.

Moreover, "Create GitHub release" now waits for both "Publish
documentation" and "Update samples" to be successful.
