Add unit tests for publishPlugin task rename

- Add comprehensive Spock tests validating publishPlugin task behavior
- Test task registration with different publishing configurations
- Test task dependencies for registry and GitHub publishing
- Test task is not created when no publishing is configured
- Add required test dependencies (Spock framework)
