Aspnetcore.docs: Add more details in the middleware section for Map**

[Nothing-Works]

Issue description

I think we should add more details for MapWhen in the middleware section. As it stops executing the rest of the pipeline when the delegate returns true. I do not think this is in the docs and this can be confusing for new people.

Whereas UseWhen will not stop the execution and I can not find in the docs either.

Can I submit PR?

The title of this thread should read
Add more details in the middleware section for Map* #15662
instead of
Add more deatils in the middleware section for Map* #15662

I think this can be closed. It was covered in #15497.
