Describe the bug

In the releases of v6.x.x of this package, IErrorResponseProvider was removed in favor of ProblemDetails.

All the examples show how to .AddProblemDetails() but unfortunately, they all target .NET7.

How is this supposed to be handled in .NET6? I need to be able to support backwards compatibility for my error messages, but this change does not really explain how to achieve this?
