Note on model registration

1. Use ast to parse model classes from the uploaded script.
2. Add the classes and their supported tasks to the model registry file registry.yaml.
3. Run tests on HF Space to ensure the model is working as expected.
4. Push files to the Hub and sync with github repository.
5. Use HF webhook to check the status of benchmark tasks (pass, fail, null), run unfinisehd tasks and visualize the results on leaderboard. [guide]
