az vm get-instance-view not returning list when providing one ID

### Describe the bug

According [this documentation](https://learn.microsoft.com/en-us/cli/azure/query-azure-cli?tabs=concepts%2Cbash#dictionary-and-list-cli-results), commands which COULD return more than one object should return an array.

`az vm get-instance-view --ids "$MY_IDS"`

* Returns an array with objects when $MY_IDS contains more than one value.
* Returns an object when $MY_IDS contains a single value

This makes queries unreliable. For example: `az vm get-instance-view --ids "$MY_IDS" --query "[].id"`

### Related command

### Errors

No errors

### Issue script & Debug output

After having a look at them I don't think they are relevant. Please let me know if actually required and I will spare some time to remove all the sensitive information and provide the logs.

### Expected behavior

`az vm get-instance-view --ids "my-vm-id"` returns an array with a single object
