Customer feedback | az vmss create | SpotRestorePolicy Error: "InvalidParameter"

### Describe the bug

This GitHub issue is being moved from azure-docs-cli [4474](https://github.com/MicrosoftDocs/azure-docs-cli/issues/4474).

Here is a customer screen print of the reference command parameters and error:

***************************************
**Type of issue**
Code doesn't work

**Feedback**
When using this example code (with changed values for Image and ResourceGroup)

"az vmss create -n MyVmss -g MyResourceGroup --location NorthEurope --instance-count 2 --image CentOS85Gen2 --priority Spot --eviction-policy Deallocate --single-placement-group --enable-spot-restore True --spot-restore-timeout PT1H"

I get the Error "DeploymentFailed" and the details:

"code":"InvalidParameter","target":"spotRestorePolicy","message":"The value of parameter spotRestorePolicy is invalid."

(On Cloud-Shell with az --version = 2.62.0)

I also tried to set "--single-placement-group false --enable-spot-restore false" - this then worked and a vmss was deployed.

(I also tried " --single-placement-group false --enable-spot-restore true" yielding the same invalid parameter response.)
