Seems that to allow this functionality 3 lines of code needs to be changed:
terraform-provider-azurerm/internal/services/compute/shared_schema.go line 644 to accomodate for 4 new SKUs
terraform-provider-azurerm/internal/services/compute/windows_virtual_machine_resource.go line 616 to reflect new SKUs in error message
terraform-provider-azurerm/internal/services/compute/orchestrated_virtual_machine_scale_set_resource.go line 556 to reflect new SKUs in error message
