Document "env" option for eslint-import-resolver-webpack

[linvain]

I use env variable in my webpack config:

module.exports = function (env) {
    ...
}

This leads to a hell of errors:

Resolve error: Cannot read property 'production' of undefined

The issue can be resolved by adding env option to resolver settings:

  "settings": {
    "import/resolver": {
      "webpack": {
        "env": "development"
      }
    }
  }

But this is not documented.
P.S.: Thanks @VladimirPal (#1043)

@linvain / @ljharb , I know this is closed, but before I file a new issue, is there a way to acknowledge that environment variables exist, but not set their value? Maybe I'm misunderstanding how to use that config. My complex webpack setup allows the user to pass in additional options on the command line, but it throws all kinds of errors as were mentioned in the beginning of this issue.

I think that you might need to have a JS-based config that reads those command-line values :-/
