Learner docs: Clarify how to unsubscribe from course emails

Description

From the EdX Documentation Feedback sheet:

I would like to unsubscribe from emails but can't find a traditional format for doing so, neither did a search work.

A search for "unsubscribe" in the learner docs doesn't return any results. The docs have a Change a Course Email Preference heading, but it would be good to include the word "unsubscribe" so that searchers can find this topic.
