update google tracking code for CFE

[toloudis]

The main change is to replace the current Google Tag Manager container ID of "GTM-55J7XSR" to the new container ID of "GTM-5ZMGFX6N". They appear in the below snippets (showing the new container ID) where it was originally installed:

1. This code is in in the of the page:

<!-- Google Tag Manager -->
<script>(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-5ZMGFX6N');</script>
<!-- End Google Tag Manager -->

2. This code is after the opening tag:

<!-- Google Tag Manager (noscript) -->
<noscript><iframe src="https://www.googletagmanager.com/ns.html?id=GTM-5ZMGFX6N"
height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript>
<!-- End Google Tag Manager (noscript) -->
