Use Gatsby Head API

Support for the Gatsby Head API was added in [email protected].

Gatsby includes a built-in Head export that allows you to add elements to the document head of your pages.

Compared to react-helmet or other similar solutions, Gatsby Head is easier to use, more performant, has a smaller bundle size, and supports the latest React features.

We'll have to change some things on the consumer websites as well, but our head tags have needed a refactor for a while so this may be a perfect opportunity!
