Reviews missing 'updated' property

[alexstyl]

The read me mentioned that fetching reviews will include the updated property (link to readme).

However, using the following code does not include the update property:

const reviews = await store.reviews({
        id: appId,
        sort: store.sort.RECENT,
    })

returned objects look like this:

{
  "id": "10336812000",
  "userName": "XXX",
  "userUrl": "https://itunes.apple.com/us/reviews/000",
  "version": "0.0.0",
  "score": 5,
  "title": "TITLE",
  "text": "TEXT",
  "url": "https://itunes.apple.com/us/review?id=000"
}

everything else seems fine, other than the updated property missing
