[bmish]

Ember Times review template

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

What it does

Add a section covering:

• RFC merged for deprecation of Ember array prototype extensions
• Ember array prototype extensions disabled by default in ember-cli blueprint
• Lint rule autofixer implemented for Ember array prototype extensions

NOTE: This is a draft until:

• DONE: This is released in ember-cli:
  • https://github.com/ember-cli/ember-cli/pull/10017
• DONE: The lint rule autofixer is released as v11.1.0 of eslint-plugin-ember:
  • https://github.com/ember-cli/eslint-plugin-ember/issues/1556

I'm happy to add additional detail to this section as requested. Others are also welcome to follow-up to my PR to further flesh out this section.
