ArcGIS Experience Builder Fast Refresh

[Dvirus]

Adding FastRefresh to ArcGIS Experience Builder Developer Edition.

FastRefresh is now part of create-react-app

(https://reactnative.dev/docs/fast-refresh)

 ArcGIS Experience Builder (DE) is not running on webpack-dev-server

But there is React Refresh Webpack Plugin

https://github.com/pmmmwh/react-refresh-webpack-plugin

supporting ts-loader

And can be use also as webpack-hot-middleware 

Just need to check if it's also working on Koa😉
