fix: add Process.sleep to async broadcast tests and update Renovate workflow for Forgejo

- Fix PacketConsumerTest timing issues by adding Process.sleep(50) after handle_events
  to wait for async broadcast tasks to complete before assertions
- Update Renovate workflow to use Docker container directly instead of GitHub Action
- Use full GitHub URL for checkout action to work with Forgejo Actions
