Update configure documentation for Kebab formater

As per:
https://masstransit.io/documentation/configuration#endpoint-name-formatters

But the class has a bool param:
https://github.com/MassTransit/MassTransit/blob/9a6916d681b3601a3ff8b4830027d34a6a05fb93/src/MassTransit/Configuration/KebabCaseEndpointNameFormatter.cs#L28

I did a copy and past to my code and it didn't compile. 

Fix the doc to prevent that happened to next person googling the issue.

-x.SetEndpointNameFormatter(new KebabCaseEndpointNameFormatter(prefix: "Dev"));
+x.SetEndpointNameFormatter(new KebabCaseEndpointNameFormatter(prefix: "Dev", includeNamespace: false));
