doc: edit text for DEP0013

* v10.0.0 -> Node.js 10.0.0
* Parenthetical with URL rather than "PR" as a lot of people may not
  know what "PR" stands for but they will know what a URL is. Plus not
  hiding the URL means the text is more copy/paste-able. In this
  particular case, "PR 12562" is not more useful or informative than
  nodejs#12562 so just use the URL.
