Wrong hyperlink at the "Getting Started" page (v2)

Hi there!

I've noticed that, at https://developers.artsy.net/v2/start if you click at the hierarchy at the top of the screen to get back to the "Public API Documentation", you get into the v1 of the page, and not at the v2.

Also, there seems to be some options missing at v2, when compared to v1.
