SDK needs to support model filters for AllRetainedMessages

Is your feature request related to a problem? Please describe the problem.

I want to make requests to the AllRetainedMessages endpoint. For paid subscriptions this requires the Model parameter to be set.

Doing this doesn't work yet.

    RequestInformation historicalMessagesRequest = _graphServiceClient
        .Users[userGuid]
        .Chats
        .GetAllRetainedMessages
        .ToGetRequestInformation(configuration =>
        {
            // configuration.QueryParameters.Model = "ModelA" ; todo this doesn't work yet
        });

I have a work around that's low level and gross.

historicalMessagesRequest.UrlTemplate =
    "{+baseurl}/users/{user%2Did}/chats/getAllRetainedMessages()" +
     "{?%24count,%24expand,%24filter,%24orderby,%24search,%24select,%24skip,%24top,model*}";

 historicalMessagesRequest.QueryParameters["model"] = "ModelA";

You have to both manually add your licensing model to the query parameters, and adjust the url template so that this model goes to the actual request url made by the SDK. This is hokey and janky.

Describe the solution you'd like.

Can we just have this work, for parity with AllMessages?

    RequestInformation historicalMessagesRequest = _graphServiceClient
        .Users[userGuid]
        .Chats
        .GetAllRetainedMessages
        .ToGetRequestInformation(configuration =>
        {
            configuration.QueryParameters.Model = "ModelA";  // Just make this compile and work
        });

Additional context?

No response

Start at the GetAllRetainedMessages request entry point and inspect how its ToGetRequestInformation configuration exposes QueryParameters, comparing it with AllMessages. Trace the generated request URL handling to confirm where the model parameter must be declared. Done means configuration.QueryParameters.Model compiles and the model value is included in requests to AllRetainedMessages.
