Fixups to quickstart (#4983)

Summary:
I tried running the quickstart with 19 and hit two issues:

1. We need to update Babel to match the new compiler default of es modules: #4982
2. ~~We need to update our TS types to allow omitting store: DefinitelyTyped/DefinitelyTyped#72689 Merged and shipped

Until those land, we should not have users expect those things to work

Pull Request resolved: #4983
