title: Move product meta to the description tab in WooCommerce
body: <p>How to move the product meta to the beginning of the product description tab?
  I try:</p>
  
  <pre><code>remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_meta', 40 );
  add_action( 'woocommerce_product_tabs_description', 'woocommerce_template_single_meta', 10 );
  </code></pre>
  
  <p>Remove works, but <code>add_action()</code> doesn't.</p>
