The 'ecmaFeatures' config file property is deprecated

[GitTom]

The docs suggest

  "ecmaFeatures": {
    "jsx": true
  },

But for me, using eslint 4.19.0, I get the following warning:

[eslint] The 'ecmaFeatures' config file property is deprecated, and has no effect.

I think the solution is to use this instead

  "parserOptions": {
      "ecmaFeatures": {
          "jsx": true,
          "modules": true
      }
  },

Hi @GitTom, thanks for reporting, feel free to make a PR with an update!

The solution by @GitTom fixed this for me too!

I will go ahead and submit a pull request for this in the docs since I don't see one open, and the issue is still present.
