Update .babelrc example for use with TS

[ekafyi]

Using the .babelrc example from "Using with Typescript" in the README breaks async function.

Error: {"errorType":"ReferenceError","errorMessage":"regeneratorRuntime is not defined"}

Relevant issues:

• ReferenceError regeneratorRuntime is not defined babel/babel#9849
• https://binyamin.medium.com/enabling-async-await-and-generator-functions-in-babel-node-and-express-71e941b183e2

Fix: Add config object in @babel/preset-env

Thanks @ekafyi, I added a missing comma and fixed the formatting to use spaces
