template update

Unfortunately `react-app-rewired` is outdated and does not support CRA 2.0.
`react-app-rewired` shows some alternatives. One of those is `craco`. It is really easy to setup and offers recipes and plugins. With the use of craco and a plugin it is really easy to setup CRA with antd.

Here my template with create-react-app, antd & craco:

I think this is a cleaner solution. If you want, you can use it for this template. ✌️

Review the current create-react-app template and compare its react-app-rewired setup with the linked react-antd-setup example. Check how CRA 2.0 compatibility and antd integration are currently handled; done means the template uses the proposed approach and works without the outdated setup.
