Document how to disable Actions in GitHub

[plocket]

Yes, you can disable Actions in GitHub.

For an organization: https://docs.github.com/en/organizations/managing-organization-settings/disabling-or-limiting-github-actions-for-your-organization#managing-github-actions-permissions-for-your-organization

For a repository: https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/enabling-features-for-your-repository/managing-github-actions-settings-for-a-repository#managing-github-actions-permissions-for-your-repository

I'll make this into a documentation issue too, thanks!

Edit: disabling just that particular workflow will help people who want to be able to run other actions:

You can also keep your other actions running and disable just that workflow: https://docs.github.com/en/actions/managing-workflow-runs/disabling-and-enabling-a-workflow
