Docs feedback: Mention resetting runner token via gitlab-rails console

Several users on Stack Overflow make a mistake by not copying secrets when moving/restoring a GitLab instance. When they want to access runner pages or admin pages they get a 500 error because of a decryption error. So in their view they can't reset the token and their GitLab is broken.

Maybe a good idea to add to the documentation a way to reset the token through rails console?
