Is your feature request related to a problem? Please describe

I'm using V3 API (instead of V2) to retrieve listings and listings having variations

• recently 'inventory' has been added to the includes of getListing with #236 🙏 thanks for that; this prevent me additional api call.

• about variations translations:

• • I'm always using an additional getListingInventory to retrieve 'fr' translations of variations property_names
• • I also do need variation property_values.values translation : that is traced (& commented april) in #431

And I created this ticket to know if you plan to add to includes "variationImages' too ? this is the way to retrieve the relation between : a product property_id, a product property_value_id, and an image_id

for now I'm using getListingVariationImages

Describe the solution you'd like

having variationImages accepted as includes enum value.

This will add to the result an addotionnal field ; example

<listingDocHere>
...
variationImages: [
    {
      "property_id": 102868018123,
      "value_id": 112744446756,
      "value": "Quartz",
      "image_id": 3215768148
    },
    {
      "property_id": 102868018123,
      "value_id": 112394957206,
      "value": "Améthyste",
      "image_id": 3215768258
    },
    {
      "property_id": 102868018123,
      "value_id": 1014722082046,
      "value": "Labradorite",
      "image_id": 3215768376
    }
  ]

Describe any alternatives you've considered

As alternative I will keep my additional api call to getListingVariationImages
