[Feature]: Get-AzAutomationSoftwareUpdateConfiguration Include includedKbNumbers and excludedKbNumbers

### Description of the new feature

Currently the Get-AzAutomationSoftwareUpdateConfiguration does not return the Included KB Numbers and the Excluded KB Number. These IDs are available on the REST API per the MS documentation (https://docs.microsoft.com/en-us/rest/api/automation/software-update-configurations/get-by-name):

https://management.azure.com/subscriptions/[subscriptionID]/resourceGroups/[resourceGroup]/providers/Microsoft.Automation/automationAccounts/[automationAccount]/softwareUpdateConfigurations/[ScheduleName]?api-version=2017-05-15-preview

### Proposed implementation details (optional)

Ideally this can be built into the object

Start at the Get-AzAutomationSoftwareUpdateConfiguration cmdlet and trace how the Automation REST API response is mapped into its returned object. Check the existing tests for this cmdlet before making the change. Done means the includedKbNumbers and excludedKbNumbers values from the REST response are exposed and covered by passing tests.
