az lab vm show and az lab vm list response always have applicableSchedule and scheduleParameters as null

### Describe the bug

The json response for a VM in either 'az lab vm show' or 'az lab vm list' always has these 2 fields as null:
- applicableSchedule
- scheduleParameters
I tried several permutations on a Lab VM to opt-in or opt-out of the shutdown schedule and change the shutdown time and time zone. The 2 fields show as null no matter what the VM settings.
I did notice that opt-in to auto start adds a Tag to the Lab VM.
I'm trying to produce a report that will let a lab admin know if a lab VM has been opted out of shutdown time or is running on a different shutdown schedule

### Related command

az lab vm show -g myGroup --lab-name myLabName --name myVmName
az lab vm list -g myGroup --lab-name myLabName

### Errors

No error messages are apparent to the user

### Issue script & Debug output

nothing apparent in debug - commands complete successfully

### Expected behavior

applicableSchedule and scheduleParameters should not always be null
