Blame for scripts/push_space.py

"""Upload the public demo to a Hugging Face Docker Space. The upload holds the repository's files as they are in the
working tree (tracked, plus new files git does not ignore), with deploy/space/Dockerfile and deploy/space/README.md as
the Space's Dockerfile and README. The Space then builds the image and runs deploy/space/start.sh.

    python scripts/push_space.py sparklabuofu/MiniWeb-demo --dry-run    # list what would change
    python scripts/push_space.py sparklabuofu/MiniWeb-demo              # creates the Space when it does not exist

Needs a token that can write to the namespace (`huggingface-cli login`, or HF_TOKEN).
