Support TypeScript

[jimthedev]

Need to do a new patch including react#5827

[jimthedev]

For now you can:

npx create-react-app my-new-react-project --scripts-version @spscommerce/ui-react-scripts --typescript
cd my-new-react-project
yarn add typescript @types/node @types/react @types/react-dom @types/jest

then edit src/react-app-env.d.ts to remove all contents for now.
