Documentation: Networking page links to navigators / next page are broken

[valscion]

http://facebook.github.io/react-native/releases/next/docs/network.html

1. To manage the transition between these screens, you will need to learn about navigators.

   This "navigators" links is broken and instead redirects to the documentation front page.

2. The "Next →" link is also broken on that page

I'm just following the We Need Your Help instructions here 😄
