[Website] Add Common Room script to website

[calon-pulumi]

Common Room app just added new features to capture web visits on our website.

From this guide, we'd like Step 1 and 2 followed. https://docs.commonroom.io/using-common-room/website-visitor-tracking/setup

Our unique web tracking script copied over from the app us:

<script> (function() { if (typeof window === 'undefined') return; if (typeof window.signals !== 'undefined') return; var script = document.createElement('script'); script.src = 'https://cdn.cr-relay.com/v1/site/a725b5ba-75f1-44dc-b250-11023fc10b9d/signals.js'; script.async = true; window.signals = Object.assign( [], ['page', 'identify', 'form'].reduce(function (acc, method){ acc[method] = function () { signals.push([method, arguments]); return signals; }; return acc; }, {}) ); document.head.appendChild(script); })(); </script>
