Docker container action does not get inputs that have hyphen in the name

Code of Conduct

• I have read and agree to the GitHub Docs project's Code of Conduct

What article on docs.github.com is affected?

https://docs.github.com/en/actions/creating-actions/creating-a-docker-container-action

What part(s) of the article would you like to see updated?

So I followed the instructions on the page, and used an input like so:

        with:
          who-to-greet: Arnold

it turns out, after long trial and error, that hypen makes it not available on the Docker container.

I would suggest to make that a warning callout, and use underscores in the example.

I'm ready to make that PR if you agree with this, just let me know.
