ResponseStatusException does not use the reason to set the "detail" field

[ydemartino]

Affects: 6.0

The javadoc for the ResponseStatusException is

 * Subclass of {@link ErrorResponseException} that accepts a "reason" and maps
 * it to the "detail" property of {@link org.springframework.http.ProblemDetail}.

But when I set a reason, the detail is always null. It seems the class is missing getBody().setDetail(getReason());.
Or maybe this is an issue in the javadoc?
Or am I missing something?

This was the case, but was removed when adding tests for all sub-classes, with the idea that the reason isn't always what should be present to the outside world.

What I think it should say, and work, is that it uses the reason as the detail by default, but sub-classes can set the detail to something else if needed.
