Wrong Create React App version in React v17 docs

[cseas]

The migration guide for the new JSX transform on the React blog mentions that Create React App v4.0.0+ uses the new transform for compatible React versions.

Trying to use the new transform with CRA v4.0.0 will introduce a breaking bug in the application as noticed in react/create-react-app#10110

I believe CRA v4.0.1+ will be the versions that will work stable with React v17 in a typescript setup.
