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/using-workflows/workflow-commands-for-github-actions#setting-an-environment-variable

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

The names of environment variables are case-sensitive, and you can include punctuation.

This is true on Linux (and macOS).

However, my understanding is that this is at least partially untrue on Windows:
https://github.com/actions/runner/blob/cb19da9638790019f6e7be193cd4282311992b12/src/Runner.Worker/ActionCommandManager.cs#L158-L162

I say partially, because I haven't extensively tested the code paths.
