Get-AZAutomationHybridWorkerGroup returns 0 results when run against an automation account

### Description

when running the cmdlet 'Get-AZAutomationHybridWorkerGroup', no results are returned. The behavior is the same if I provide the RG and AA account names in-line or when prompted.

If I provide a known group name, the worker group is returned.

Get-AzAutomationHybridWorkerGroup -ResourceGroupName MYRESOURCEGROUP -AutomationAccountName MYAUTOMATIONACCOUNT
Get-AzAutomationHybridWorkerGroup -ResourceGroupName MYRESOURCEGROUP -AutomationAccountName MYAUTOMATIONACCOUNT -Name "HybridGroup"

ResourceGroupName : MYRESOURCEGROUP
AutomationAccountName : MYAUTOMATIONACCOUNT
Name : HybridGroup
RunbookWorker : {}
GroupType : User

NOTE: same behavior in 7.2 and 5.1

### Error output

_No response_

Start by reproducing Get-AzAutomationHybridWorkerGroup with and without -Name against the ARM hybridRunbookWorkerGroups endpoint shown in the debug output. Inspect the Az.Automation implementation for the ByAll parameter set and its handling of the successful empty response. Done means the no-name command returns existing worker groups while the named query continues to work.
