#### Overview of the Issue
I am trying to execute a Packer build for Azure with a configured Service Principal. For an unknown reason it is always trying to use a Managed Identity. I don't see any issue with my packer template, I am providing the necessary details for "client_id" and "client_secret". The variables are specified and values are correct. Has anyone seen this kind of behaviour before?

#### Reproduction Steps
This is happening with every build.
I tried several packer versions & azure plugins but it doesn't make a difference.

### Packer version
Packer v1.10.0

packer-plugin-azure_v2.0.2_x5.0_windows_amd64
packer-plugin-azure_v2.0.1_x5.0_windows_amd64
packer-plugin-azure_v1.4.5_x5.0_windows_amd64

### Simplified Packer Template
source "azure-arm" "test" {

#Azure Info
subscription_id = "${var.subscription_id}"
client_id = "${var.AZURE_CLIENT_ID}"
client_secret = "${var.AZURE_CLIENT_SECRET}"
cloud_environment_name = "Public" # China, Germany, or USGovernment

#Packer Azure
build_resource_group_name = "rg-test # Resource Group needs to exist before!!
managed_image_name = "${var.managed_image_name}-${formatdate("YYYY-MM-DD-hhmm",timestamp())}"
managed_image_resource_group_name = "rg-test"
managed_image_storage_account_type = "Premium_LRS" # Standard_LRS

### Operating system and Environment details

Windows 11, Local

### Log Fragments and crash.log files
`==> Some builds didn't complete successfully and had errors:

Start by reproducing the failure with the supplied Azure ARM template and review the logged request to the VM metadata endpoint. The issue is done when valid client_id and client_secret settings use service-principal authentication without attempting the unavailable managed-identity metadata service.
