Setting "managed_image_zone_resilient": "false" for a Azure Image is not setting properly.

_This issue was originally opened by @danmanrique as hashicorp/packer#10526. It was migrated here as a result of the [Packer plugin split](https://github.com/hashicorp/packer/issues/8610#issuecomment-770034737). The original body of the issue is below._

#### Overview of the Issue

Setting the property in the builders part of the json file for "managed_image_zone_resilient": "false" for a Azure Image is not setting properly. I am building a WindowsClient image in Packer. After the build, I import the image via Terraform to subsequently store the image in a Gallery. When I run Terraform Plan after the import for the rest of the deployment, I get "+zone_resilient = false # forces replacement". In Azure, the state on the Image shows "ZONE RESILIENCY: Disabled."

I checked the Terraform State file and the property is null. I think the issue is in the Terraform import process of this property or the interrupt between the two.

I did find a workaround. I ignored the zone-resilient attribute, and I am able to move forward with the workaround.

```hcl
lifecycle {
ignore_changes = [
zone_resilient,
source_virtual_machine_id,
]
}
```

#### Reproduction Steps

Create a deployment.json.
In the deployment json:
First, without setting the property.
Second, setting the managed_image_zone_resilient = false property
On an outer script in Powershell:
Create RG
Run Packer
Import the RG
Import the Image
Run Terraform Plan

Start by tracing the managed_image_zone_resilient entry point through Azure image creation and the Terraform import boundary. Compare the request and response logs with the null value observed in Terraform state, then reproduce the two deployment.json cases and Terraform plan. Done means false remains represented consistently and no replacement is proposed for the disabled zone-resilient image.
