title: Google recaptcha is not accessibility compliant
body: <p>The google recaptcha creates a textarea that has no accessibility attributes, like aria-label.   This is causing the recaptcha to fail our accessibility scan via Siteimprove.</p>
  
  <p>I've tried adding the aria-label attribute to the textarea using javascript,  but i'm adding it to the element after it has been added to the DOM,  so i'm guessing that is why the accessibility is failing.</p>
  
  <p>Here is text from Siteimproves google extension:</p>
  
  <blockquote>
    <p>Failing requirement 4.1.2 <code>textarea</code> is empty.  This is because no label is associated  with the text area or an aria-label attribute isn't added to the textarea.</p>
  </blockquote>
