Missing `#comments` anchor on article pages

Clicking an "X comments" link from the index takes you to a URL with a #comments anchor at the end, for example: https://blog.torproject.org/blog/we-are-upgrading-our-blog#comments It's supposed to scroll you down to the comments, but the article page is missing the appropriate anchor.

This bit of HTML:

      <section>
      
    <h2>Comments</h2>

needs to change to something like this:

      <section id="comments">
      
    <h2>Comments</h2>
