Mistake in Docker Space tutorial

In the “Create The Dockerfile” section there is this line

CMD ["uvicorn", "app.main:app", "--host", "", "--port", "7860"]

This did not work for me. The line in the official repo example is

CMD ["uvicorn", "main:app", "--host", "", "--port", "7860"]

This works, so it would be good to update the tutorial for folks like me who are struggling to set up their first Space from scratch
