Deserialization error with az guestconfig guest-configuration-assignment create

### Describe the bug

Attempting to create a new azure machine configuration guest configuration assignment will fail immediately with a deserialization error. This occurs even when using the example create command [from the azure docs](https://learn.microsoft.com/en-us/cli/azure/guestconfig/guest-configuration-assignment?view=azure-cli-latest#az-guestconfig-guest-configuration-assignment-create).

az guestconfig guest-configuration-assignment create --guest-configuration-assignment-name "WhitelistedApplication" --guest-configuration-name "WhitelistedApplication" --location "westcentralus" --context "Azure policy" --guest-configuration-name "WhitelistedApplication" --guest-configuration-configuration-parameter name="[InstalledApplication]bwhitelistedapp;Name" value="NotePad,sql" --guest-configuration-configuration-setting action-after-reboot="ContinueConfiguration" configuration-mode="MonitorOnly" configuration-mode-frequency-mins=15 reboot-if-needed="False" --guest-configuration-version "1.*" --resource-group "myResourceGroupName" --vm-name "myVMName"
```

### Expected behavior

Even if the wrong parameters are given, the error message should explain the problem with the argument. It should not be a Python stack trace.
