build: Updating npm dependencies

* eslint-config-wikimedia: 0.5.0 → 0.15.0
  The following rules are failing and were disabled:
  * no-prototype-builtins

* grunt-eslint: 20.1.0 → 22.0.0
* grunt-stylelint: 0.10.1 → 0.13.0
* stylelint-config-wikimedia: 0.4.3 → 0.8.0
  The following rules are failing and were disabled:
