Add tracking to the "Deploy to Netlify" buttons and the "Share to..." buttons

Current state

Currently we know the level of traffic that the Static Gen site gets, but not how the page is actually used by visitors. Since it's got relatively high traffic already, it would be good to understand how visitors are using the page so that we can make updates that help bring them into the product.

Future state

Implement tracking so we know when someone clicks the "Deploy to Netlify" button. This will help us understand visitor intent, and as we scale out our data tracking we can eventually track the success of someone who has hit the "Deploy to Netlify" button and then successfully deployed a site.

Additionally we should track the "Share" buttons for Twitter and Reddit to understand if this is being used or not.
