Have the ErrorResponse.Builder take in a custom ProblemDetail instance

[mzeijen]

As a user I would like to be able to create an ErrorResponse instance with a custom ProblemDetail instance, while using the default ErrorResponse.Builder via the ErrorResponse.builder and/or ErrorResponse.create methods. This makes it easier for me to provide a custom ProblemDetail class while still being able to use the builder facilities.

Currently there is no way to provide my own ProblemDetail instance to the builder, either via a method directly on ErrorResponse.Builder instance or via the ErrorResponse.create or ErrorResponse.builder methods (which is probably the preferred way).

Note: I have discussed this feature request with @rstoyanchev at Spring I/O 2023

Thanks for raising this, @mzeijen. I've added dcba947 in time for 6.1 M1 with plenty of time to refine further if needed.

Thanks for addressing this so quickly.
