az vm create command reports "Consider upgrading security for your workloads using Azure Trusted Launch VMs." when it is used to create CVMs

### Describe the bug

I am using AZ CLI to create Confidential VM. I pass the following parameters:
--security-type ConfidentialVM
--os-disk-security-encryption-type DiskWithVMGuestState

Command reports the following warning:

_Consider upgrading security for your workloads using Azure Trusted Launch VMs. To know more about Trusted Launch, please visit https://aka.ms/TrustedLaunch._

This does not make sense, since ConfidentialVM support TrustedLaunch.

### Related command

### Issue script & Debug output
