Modify “Gift Wrapping for Order” Text in Order Email

I am trying to change the text that says “Gift Wrapping for Order” to “Gift Messaging” in the order confirmation email that is sent out.

I have figured out where the copy needs to be updated to actually, change it, but I’m struggling with getting my module to work so I can override the /vendor/magento/module-gift-wrapping/Helper/Data.php file properly.

Here is my module:

app/code/Vendor/ModuleName/etc/module.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Vendor_ModuleName">
    </module>
</config>

app/code/Vendor/ModuleName/etc/di.xml

<?xml version="1.0"?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="MagentoGiftWrappingHelperData" type="VendorModuleNameHelperData" />
</config>

app/code/Vendor/ModuleName/Helper/Data.php

<?php

{
    $totals = [];

    $displayWrappingBothPrices = false;

What am I missing?
