Changed the type of withUrlOptions from string to object to accommodate missing properties.

[Playmaker5677]

Currently, withUrlOptions is defined as of type string, however, as this documentation from Microsoft shows, we could define quite a few properties there: https://learn.microsoft.com/en-us/aspnet/core/signalr/configuration?view=aspnetcore-7.0&tabs=javascript#configure-additional-options

• Inside the .withUrl method it is expected to pass object as a second parameter:

let connection = new signalR.HubConnectionBuilder().withUrl("/chathub", {
// "Foo: Bar" will not be sent with WebSockets or Server-Sent Events requests
headers: { "Foo": "Bar" },
transport: signalR.HttpTransportType.LongPolling
}) .build();

• Also inside the abp.signalr-client.js start method we are using the withUrlOptions as object:

abp.signalr.withUrlOptions.transport = transport;

In case withUrlOptions is defined as string this causes transport to be returned as undefined.

• Also, if we are deploying in web farm environment we are not able to set the skipNegotiation property if withUrlOptions is defined as string which in turn breaks the signalR connection.
