Add debugger support

[OlegPhenomenon]

To make life easier for me and perhaps for those who will still be engaged in the project, there is a cool feature in VS code, which can allow you to add the ability to debug the project on React.

Here are the templates:
Run -> Add Configuration -> Node JS

{
	// Use IntelliSense to learn about possible attributes.
	// Hover to view descriptions of existing attributes.
	// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
	"version": "0.2.0",
	"configurations": [
	
		{
			"type": "node",
			"request": "attach",
			"name": "Launch Program",
			"skipFiles": [
				"<node_internals>/**"
			],
			"port": 9229
		}
	]
}

In package.json add:
"debug": "NODE_OPTIONS='--inspect' next dev",

After run press F5 and put necessary breakpoint.

Also will be nice if we add this feature into readme.md
