[Dev] Brings back storybooks for dev #trivial

[orta]

I assume during debugging the latest react native update storybooks were removed and then not replaced afterwards, see discussion at https://github.com/artsy/emission/pull/570/files#r120094031

As I was touching it, I updated us to the latest stable release of storybooks too. 👍

git checkout orta-585-checkout

Then run xcrun simctl launch booted net.artsy.Emission once a the simulator has finished booting

To run inside Eigen (prod or beta) or Emission (beta): Shake the phone to get the Admin menu.

If you see "Use Staging React Env" - click that and restart, then follow the next step.

Click on "Choose an RN build" - then pick the one that says: "X,Y,Z"

Note: this is a TODO for PRs, currently you can only do it on master commits.
