webpack-cli 4.x 's error in the lesson

[mox692]

Hi 👋, I succeeded this lesson.

But when I run $ npm start, this error occurred.

$ npm start

> test@1.0.0 start /Users/kimuramotoyuki/react/react-typescript-samples/handson/00
> webpack-dev-server  --mode development --inline --hot --open

internal/modules/cjs/loader.js:1033
  throw err;
  ^

This issue smells similar err, caused by webpack-cli 4.x

So I think it is good way to fix the webpack-cli's version under 4.x in this lesson.

$ npm install webpack-cli@3.3.12 --save-dev
