[Eng]: Remove-AzVMExtension doesn't perform proper uninstall of the HybridWorkerExtension on the Guest OS

### Description

Hi, are there any differences between the Powershell cmldet Remove-AzVMExtension and performing the same from the Azure portal >VM's blade > Extensions > HybridExtensionWorkerExtension > Uninstall?

When performing the uninstall from the Azure portal UI, the below Registry key is deleted:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HybridRunbookWorkerV2
And the Registry entries under this HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Azure\HybridWorker\ are removed as well.

When running the `Get-AzVMExtension -ResourceGroupName "rgname" -VMName "vmname" | ? {$_.Name -eq "HybridWorkerExtension"} | Remove-AzVMExtension -Force -Verbose` cmdlet, these registry entries are not deleted and it's breaking the Set-AzVMExtension when the cmdlet is run next time, getting stuck in a "Transitioning" state and manual uninstall of the extension is required.

Is there a Powershell cmdlet that would properly uninstall the Az VM Extension?
