Summary

Based on the official docs, the current recommended way to integrate jest into a typescript project is to use ts-jest. So why not update the typescript example? 😄

Test plan

cd examples/typescript && yarn test

hmm why is CI failing
Edit: ts-jest cannot find tsconfig.json file
Edit: this is fixed on most of node versions but not node 10
Edit: looks like a snapshot mismatch on node 10, should I update it? Totally unrelated tho 🤔

should we hold off on this until they've upgraded to jest 23? feels icky getting a bunch of jest 22 deps into the tree

Ah yea, forgot to comment on the "*" thing. Maybe let's pin the deps to ^23 (becuase we're syncing different repos) and wait until ts-jest is released
