Clarify Actions Acceptable Use for self-hosted runners

[jsoref]

What article on docs.github.com is affected?

https://docs.github.com/en/github/site-policy/github-terms-for-additional-products-and-features#actions

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

GitHub Actions enables you to create custom software development lifecycle workflows directly in your GitHub repository. Actions is billed on a usage basis. The Actions documentation includes details, including compute and storage quantities (depending on your Account plan), and how to monitor your Actions minutes usage and set usage limits.

Actions and any elements of the Actions service may not be used in violation of the Agreement, the GitHub Acceptable Use Polices, or the GitHub Actions service limitations set forth in the Actions documentation. Additionally, Actions should not be used for:

In order to prevent violations of these limitations and abuse of GitHub Actions, GitHub may monitor your use of GitHub Actions. Misuse of GitHub Actions may result in termination of jobs, restrictions in your ability to use GitHub Actions, or the disabling of repositories created to run Actions in a way that violates these Terms.

None of this clearly indicates if self-hosted runners are covered/excluded.
