Refactor usage of googleAnalytics hook

[daileytj]

Describe the desired behavior

Move the useGoogleAnalytics hook from every page to the router so we don't need to use the GA hook on every page

Describe the current behavior

useGoogleAnalytics hook is being called on every page

Is this request related to a current issue?

Additional Context

In doc-it, the useGoogleAnalytics hook is used on each page (or in the markdown page wrapper component) to call GA with 'pageviews'. This works fine. Dev-docs is configured so that we don't need to do this on every page, we can actually just have it in one place in a useEffect hook in the router (any time the route changes, we trigger a page view).

Ensure that this still works with the global search as well as the icons search because these trigger a pageview to track what the end user is searching for.
