Support peer dependency TypeScript >=4

[justinbhopper]

• Version: 22.8.0

Currently the peer dependency listed for electron-webpack-ts is "typescript": "^3.8.3", which gives a warning in Yarn:

electron-webpack-ts@4.0.1" has incorrect peer dependency "typescript@^3.8.3".

Unless there are any known conflicts, I think the peer dependency should be updated to allow TypeScript >= 4 as well.
E.g. "typescript": "^3.8.3 || ^4.0.0"

I believe this might also be the reason html-webpack-plugin no longer works with electron-webpack:

npm init
npm i html-webpack-plugin@latest
npm i electron-webpack@latest

Output from the last command above:
