title: Change order item displayed meta key label in WooCommerce admin order pages
body: <p>Following <a href="https://stackoverflow.com/questions/65877051/display-a-product-custom-field-only-in-woocommerce-admin-single-orders/65877122?noredirect=1#comment116504080_65877122">Display a product custom field only in WooCommerce Admin single orders</a> answer to my previous question, which:</p>
  <ol>
  <li>Adds a Custom SKU Field (ArticleID)</li>
  <li>Saves the Custom SKU (ArticleID) as Hidden Order Item Meta Data</li>
  <li>Saves the Custom SKU (ArticleID) as Hidden Order Item Meta Data for Manual Orders</li>
  </ol>
  <p>How can I change the displayed meta key label <code>_articleid</code> on order line items section of the admin single order pages?</p>
  <p>Right now it shows the &quot;SKU&quot;, the &quot;Variation ID&quot; (for product variations) and the &quot;_articleid&quot;.</p>
  <p>I'd like to replace displayed &quot;_articleid&quot; with &quot;Article ID&quot; instead.</p>
  <p>Any help?</p>
