Add a new section about using Recipes

Documentation location/URL

Add a new section about using Recipes - https://www.drupal.org/docs/extending-drupal/drupal-recipes →

See also Drupal CMS docs - https://new.drupal.org/docs/drupal-cms/get-started/get-to-know-drupal-cm...

Perhaps an example with the minimum required steps to build a very basic recipe could be added in the User Guide -- or added on drupal.org and linked to, if that's better?
