ARM Template - Managed Identity Extension

[robhiitsd]

The ARM templates for deploying any of the single deployments such as the Vault fail with the following error:
{"code":"DeploymentFailed","message":"At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/arm-deployment-operations for usage details.","details":[{"code":"ArtifactNotFound","message":"The VM extension with publisher 'Microsoft.ManagedIdentity' and type 'ManagedIdentityExtensionForWindows' could not be found."}]}

I worked with Microsoft and they confirmed the Managed Identity Extension is deprecated and has been replaced with an explicit property.
https://learn.microsoft.com/en-us/azure/active-directory/managed-identities-azure-resources/qs-configure-template-windows-vm#enable-system-assigned-managed-identity-during-creation-of-an-azure-vm-or-on-an-existing-vm

Would like to see this template updated with that properly working property so deployments do not fail.
