activate gtm using presets

[adamtwo]

Description

This PR removes the custom script tags that attempted to install GTM and uses the presets mechanism instead. The original solution didn't work as it didn't inject the mandatory markup in the body section:

<!-- Google Tag Manager (noscript) -->
<noscript><iframe src="https://www.googletagmanager.com/ns.html?id=GTM-PPXTTZ2"
height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript>
<!-- End Google Tag Manager (noscript) -->

What's included?

• GTM added using presets

I've checked the preview, and it has the right markup. Please note, by Docusaurus doesn't render GTM when you do npm run start . They don't want to publish metrics from test instances. The GTM markup is included only when you build with npm run build.
