📝 Docs: Mention how to use in npm scripts

[amilajack]

A nice addition would be to use this as an npm script:

// package.json
{
  "scripts": {
    "test": "package-json-validator"
  }
}

[amilajack]

I think you need to add this as a .bin for this to work

Would something like `"test": "npx package-json-validator -w -r --spec npm package.json" work if you're using > npm 5.x

[LinusU]

You should be able to just use "test": "pjv", since that is the name of the bin:

Marking as a docs issue. Let's add a mention to the README.md of how to do this!
