Adjust lint rule wording in issue 203

[bmish]

Ember Times review template

• [ ] Add your name to top and bottom
• [ ] Put emoji in writeup title
• [ ] Add a short blurb (could be the title) to the beginning
• [ ] Link to external article/repo/etc in paragraph/body text, not just the writeup title (link in writeup title is optional now)
• [ ] Add the contributor in the post in format "FirstName LastName (@githubUserName)" linked to their GitHub account
• [ ] Check that all links work

What it does

Adjust the lint section wording to reflect that the ember/no-array-prototype-extensions lint rule may be removed from the recommended config.
