not checking for prop-types validation

[AnthonyLamot]

When I leave out PropTypes I don't get the expected error.

I thought this might've been related to #1958, but when I downgraded to 7.10.0 it made no difference.

I've been away from React for a couple of months but I really miss these Eslint errors now! 😄

Note that I created my app using create-react-app. Not sure if that's causing the problem?

devDependencies:

  "devDependencies": {
    "eslint": "^5.6.1",
    "eslint-config-airbnb": "^17.1.0",
    "eslint-plugin-import": "^2.14.0",
    "eslint-plugin-jsx-a11y": "^6.1.2",
    "eslint-plugin-react": "7.10.0"
  }

Config:

{
    "extends": ["extends:airbnb", "eslint:recommended", "plugin:react/recommended"],
    "rules": {
        "react/jsx-filename-extension": [2, { "extensions": [".js", ".jsx"] }],
        "implicit-arrow-linebreak": ["warning", "beside"],
        "react/proptypes": [1],
        "react/forbid-prop-types": [0]
    },

    },
    "plugins": [
        "react"
      ]
}

Added extends: too much. 🦆
