### Description

Hi Everyone

I am trying to use the caf-enterprise-scale module to deploy the landing zone structure. I have copied the templates below.
https://github.com/Azure/terraform-azurerm-caf-enterprise-scale/wiki/%5BExamples%5D-Deploy-using-multiple-module-declarations-with-orchestration
After I created those files and folders and tried to run terraform plan, but it was an error that as the below contents

│ Error: unable to build authorizer for Resource Manager API: could not configure AzureCli Authorizer: could not parse Azure CLI version: launching Azure CLI: exec: "az": executable file not found in %PATH%
│
│ with provider["registry.terraform.io/hashicorp/azurerm"],
│ on main.tf line 15, in provider "azurerm":
│ 15: provider "azurerm" {

Could someone help me to take a look into this?

Thanks a lot

#### Screenshots

#### Additional context

Start with the provider blocks in main.tf and modules/core/main.tf, then run terraform plan using the listed Terraform and azurerm versions to confirm the authorizer failure. Compare the repository's Azure and Terraform guidance with the reproduction; done means identifying a repository-owned documentation or configuration change, since the issue currently reports an environment error without naming a project file to modify.
