title: Hide product title and categories on product page
body: <p>How could I hide product title and categories on a single product page in WooCommerce:
  <img src="https://i.stack.imgur.com/XTqDi.png" alt="enter image description here"></p>
  
  <p>I know I can edit/comment the source code but then I have to manually do it after each update. Is there a function I can add to theme functions.php that can remove product title and categories from single product page?</p>
