[BUG] Cannot set destination path for SSH public keys

Describe the bug: A clear and concise description of what the bug is.

https://github.com/Azure/azure-cli/issues/12459

When I use Azure CLI to create a VM and specify ssh key path, I get an error.

Destination path for SSH public keys is currently limited to its default value /home/[username]/.ssh/authorized_keys due to a known issue in Linux provisioning agent.

CLI command:

az vm create --resource-group myResourceGroup --name myVM --image UbuntuLTS --admin-username azureuser --generate-ssh-keys --ssh-dest-key-path './'
