Ember [ships with this now](https://www.emberjs.com/api/ember/release/classes/Ember.Templates.helpers/methods/array?anchor=array) so I don't think there's any need to mention [`ember-array-helper`](https://github.com/kellyselden/ember-array-helper). e.g. update this section https://github.com/EmberMN/ember-cli-plotly#static
