DeleteInstallApprovalRule requires ruleId not Name

[berglundth]

On attempting to remove a rule I got this error:

VERBOSE: [SESTO869]: LCM:  [ Start  Resource ]  [[UpdateServicesApprovalRule]RemoveDefaultApprovalRule]
VERBOSE: [SESTO869]: LCM:  [ Start  Test     ]  [[UpdateServicesApprovalRule]RemoveDefaultApprovalRule]

When looking at the function signature of DeleteInstallApprovalRule it seems like it accepts the ruleId and not the name:

TypeName   : Microsoft.UpdateServices.Internal.BaseApi.UpdateServer
Name       : DeleteInstallApprovalRule
MemberType : Method
Definition : void DeleteInstallApprovalRule(int ruleId), void IUpdateServer.DeleteInstallApprovalRule(int ruleId)

And here's the calling code DSCResources/MSFT_UpdateServicesApprovalRule/MSFT_UpdateServicesApprovalRule.psm1 - Row 242

                "Absent"
                {
                    $WsusServer.DeleteInstallApprovalRule($Name)
                }
