[node-plop] instanceof Array is not working with array from vm script

[niandalu]

There's a validation for generator.actions while running runGeneratorActions.

I'm using vm to load plopfile and programmatically register it to node plop api instance.
But the instanceof Array would fail when the actions come from vm script. Maybe node-plop should use Array.isArray instead.

const vm = require('vm')
const s = new vm.Script(`[]`).runInNewContext()
s instanceof Array // false
Array.isArray(s) // true
