az vm create gives warning about default public IP SKU changing even when no public IP is being created

az feedback auto-generates most of the information requested below, as of CLI version 2.0.62

Related command
az vm create

Describe the bug
When creating a VM without a public IP address, you get this irrelevant warning:

It is recommended to use parameter "--public-ip-sku Standard" to create new VM with Standard public IP. Please note that the default public IP used for VM creation will be changed from Basic to Standard in the future.

Since that change won't affect VMs created with no public IP address, that warning in this case is just noise.

To Reproduce
az vm create [...] --public-ip-address ""

Expected behavior
Since no public IP address is being created, there should be no message saying the type of public IP address that is being created is going to change.

Environment summary
Cloud Shell bash

Additional context
This warning comes from here:

azure-cli/src/azure-cli/azure/cli/command_modules/vm/custom.py

Lines 913 to 920 in 5352ca8

	# In the latest profile, the default public IP will be expected to be changed from Basic to Standard.
	# In order to avoid breaking change which has a big impact to users,
	# we use the hint to guide users to use Standard public IP to create VM in the first stage.
	if public_ip_sku is None and cmd.cli_ctx.cloud.profile == 'latest':
	logger.warning(
	'It is recommended to use parameter "--public-ip-sku Standard" to create new VM with Standard public IP. '
	'Please note that the default public IP used for VM creation will be changed from Basic to Standard '
	'in the future.')
