Update release notes link for new website

On the new website the URL is:

  https://www.gerritcodereview.com/2.14.html

instead of:

  https://www.gerricodereview.com/releases/2.14.md

Remove the /releases/ path and replace .md with .html.

Also the patch release anchors named "#2.14.1" no longer work and are
replaced with "#2141". Strip the dots out when generating the anchor.
