`azure_tags` are not carried to the `artifactTags` on the Azure proxy resource

[alguimodd]

Overview of the Issue

When creating a Compute Gallery Image using Packer, azure_tags are correctly applied to the resource on the owner subscription, but if the Image Version is fetched from another subscription using the Azure proxy resource the artifactTags returned is an empty list.

Reproduction Steps

1. Create an image with Packer with azure_tags set.

sig image-version list -r GalleryName -g gallery_resource-group -i imageDefinitionName
[...]
    "tags": {
      "key1": "value1",
[...]

az sig image-version list-shared --gallery-unique-name GalleryUniqueID -i imageDefinitionName --location westus2 --shared-to tenant 
[
  {
    "artifactTags": {},
[...]
