[all pages] analytics code

Please add this (to the bottom) of all pages, so we can get analytics data with other pages such as ARIA APG, ACT Rules, Supplemental Guidance, and other WAI website pages. Thanks.

<!-- Matomo -->
<script>
  var _paq = _paq || [];
  /* tracker methods like "setCustomDimension" should be called before "trackPageView" */

  _paq.push(['trackPageView']);
