UPDATE

This PR adds an inline resource to our web-analytics script hosted at https://docs.mapbox.com/analytics.min.js to this dev tool. It sets up basic mbxMetadata to properly categorize this tool and initializes webAnalytics turning Marketo munchkin off in this instance.

// eslint-disable-next-line no-undef
initializeMapboxAnalytics({
  marketoMunchkin: false
});

This PR also removes older GA tracking codes which are no longer needed.

If approved, I will deploy this update via npm run deploy
