Docker docs create a container that does not work in single-stack ipv6 environments

Name of the Streamlit feature whose docs need improvement: Create a Dockerfile

What you think the docs should say:
The ENTRYPOINT should not have this argument: "--server.address=0.0.0.0". This makes the app not bind to [::], causing issues in our ipv6-only k8s clusters.

We have a Dockerfile that says this instead: CMD ["streamlit", "run", "home.py", "--server.port=8501", "--browser.serverAddress=localhost"].

I'm not sure if this is the best, but it does two things right:

1. Binds to [::]:8501 and 0.0.0.0:8501
2. Makes it so when you docker run, the URL provided to access streamlit works

Additional improvements:
You may want to bump the image to python3.11 or later, as 3.9 is EOL soon.
