FEI-4957.4: Run codemod to convert files to TypeScript (#526)

## Summary:
This changeset was generated using the follow commands:
- cd ../flow-to-typescript-codemod

- // manually change 'export {* as jest} from "jest"' to be 'export * as jest from "jest"' in wonder-stuff
- yarn typescriptify fix --autoSuppressErrors --jiraSlug FEI-5011 -p ../wonder-stuff --config ../wonder-stuff/tsconfig.json
- // manually rename prettierrc.ts to prettierrc.js
