title: Change "Shipping" label in Woocommerce email table totals?
body: <p>I am customizing the order email template in WooCommerce and need to change the title of "Shipping" to "Delivery," as well as change "Shipping address" to "Delivery address". I tried a plugin, "Say What" that would change the text but it did not work. There is a loop that handles all of this information.</p>

  <p>This is the code on line 52 in the "email-order-details.php" page.  </p>
  
  <pre><code>if ( $totals = $order-&gt;get_order_item_totals() ) {
                  $i = 0;
                  foreach ( $totals as $total ) {
                      $i++;
                      if($total['label'] === "Shipping"){
                          //make second-last above total somehow
                      }
                      else{
                          ?&gt;&lt;tr&gt;
                          &lt;th class="td" scope="row" colspan="3" style="text-align:&lt;?php echo $text_align; ?&gt;; &lt;?php echo ( 1 === $i ) ? 'border-top-width: 4px;' : ''; ?&gt;"&gt;&lt;?php echo $total['label']; ?&gt;&lt;/th&gt;
                          &lt;td class="td" style="text-align:left; &lt;?php echo ( 1 === $i ) ? 'border-top-width: 4px;' : ''; ?&gt;" colspan="1"&gt;&lt;?php echo $total['value']; ?&gt;&lt;/td&gt;
                          &lt;/tr&gt;&lt;?php
                      }
                  }
              }

  <p>I assume this is a filter hook, but I am not sure how to use it. </p>
