unable to get available ips in a subnet

### Describe the bug

I was trying to get available IPs with command:

az network vnet subnet list-available-ips --resource-group myRG --vnet-name myVNet --name mySubnet

and get the following response:

[
'list-available-ips' is misspelled or not recognized by the system.
Did you mean 'list-available-delegations' ?

Examples from AI knowledge base:
az network vnet subnet list -g MyResourceGroup --vnet-name MyVNet
List the subnets in a virtual network.
]

### Related command

az network vnet subnet list-available-ips --resource-group myRG --vnet-name myVNet --name mySubnet

### Errors

'list-available-ips' is misspelled or not recognized by the system.
Did you mean 'list-available-delegations' ?

Examples from AI knowledge base:
az network vnet subnet list -g MyResourceGroup --vnet-name MyVNet
List the subnets in a virtual network.
