title: ol/controls/default not a function in OpenLayers 7.1
body: <p>With OpenLayers 6.15.1, I can use the following code in my map options:</p>
  <pre><code>controls: ol.control.defaults({
      zoom: true,
      attribution: true,
      rotate: false
  }),
  </code></pre>
  <p>With OpenLayers 7.1, this does not work anymore. I get an error:</p>
  <blockquote>
  <p>Uncaught TypeError: ol.control.defaults is not a function</p>
  </blockquote>
  <p>Does anyone could explain to me what I have to change in my code?
  I have found nothing explicit in the OpenLayers official documentation online about ol/control/defaults that could explain this error.</p>
  <p>Thanks, Thierry</p>
