[FEATURE REQ] Exclude {id} from rule-path-lower-case-id

[denisbredikhin]

Please describe the feature.

With the current default Saunter configuration it generates errors based on the rule rule-path-lower-case-id in case when path contain {id}. But this route template is very popular, it is used a lot in ASP.NET documentation: https://learn.microsoft.com/en-us/aspnet/core/fundamentals/routing?view=aspnetcore-9.0 Maybe it is a good idea to exclude such paths from the rule?
