Update Set-CsOnlinePSTNGateway.md

removed [-GenerateRingingWhileLocatingUser <Boolean>] and its description being Ringback Bot has been deprecated and the public documentation how to Set up RingBackBot for Direct Routing is no longer available, but removing this parameter from PS cmdlets was not completed, generating confusion and support tickets around this topic.

-### -GenerateRingingWhileLocatingUser
-This parameter is applicable only for Direct Routing in non-media bypass mode. Sometimes inbound calls from the public switched telephone network (PSTN) to Teams clients can take longer than expected to be established. This can occur for various reasons. When this happens, the caller might not hear anything, the Teams client doesn't ring, and some telecommunications providers might cancel the call. This parameter helps to avoid unexpected silences that can occur in this scenario. When enabled for inbound calls from the PSTN to Teams clients, a distinctive audio signal is played to the caller to indicate that Teams is in the process of establishing the call.
