Add GA with Anonymous IP tracking

[mgdesign]

Since we don't have any data on how visitors use the company playbook, I suggest to add GA (with anon IP tracking to avoid adding the cookie banner).

OK, we'll also add a small cookie policy information either in the homepage or a separated one.

I'll include that page in the PR then, and we can discuss the content of it.

Thank you for answering

This one is a good starting point: I'd like to rephrase it a bit and make it to the point with what we use: https://www.careaptitude.com/en/index.html

Please add this tracking code with anonymization ip configured:

<!-- Global site tag (gtag.js) - Google Analytics -->
<script async src="https://www.googletagmanager.com/gtag/js?id=UA-62993647-4"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'UA-62993647-4' , { 'anonymize_ip' : true }) ;
</script>
