title: WooCommerce hooks - Product update deliver variation objects instead of IDs
body: <p>When receiving a product updated hook from WooCommerce, the payload contains a 'variations' array, which, however, only contains the IDs of the variations that belong to the updated product.</p>
  
  <p>How can I send the actual variation objects along with the product updated payload, instead of only the IDs of the variation (this way, I wouldn't need to send another request to the variations resource of the REST API to fetch them).</p>
  
  <p>Thanks!</p>
