rfc 9457 error bodies

[Gitznik]

RFC 9457 defines the "application/problem+json" media type: https://www.rfc-editor.org/rfc/rfc9457.html#section-1-6

Using JSON on a httpexpect.Response that contains an error response according to RFC 9457 fails, as it does not expect this media type.

Can we have support for working with this somehow?
