"Does repair vm requires public ip" No opion does not work

### Describe the bug

I did 「az vm repair create -g rgname -n vmname --repair-username username --repair-password passwordinfo --enable-nested --verbose」with prompt 「"Does repair vm requires public ip" No」.
However public ip has been assigned on repair vm even though I set「"Does repair vm requires public ip" No」

We can repro easily.

Upon checking the az vm repair debug logs internal "az vm create" command set --public-ip-address repair-vm-wins_PublicIP.
I think should be set --public-ip-address "" in the case user set「"Does repair vm requires public ip" No」.
