feat: Add Docker Hub propagation wait and HuggingFace Spaces build restart

The code changes include adding a new step in the `.github/workflows/docker-build.yml` file to wait for Docker Hub to propagate. Additionally, a new script `factory_restart_space.py` is added in the `scripts` directory to restart the HuggingFace Spaces build. This script uses the `HfApi` and `rich` libraries to interact with the HuggingFace Hub API and print the space runtime.
