Custom success and error content-types in chi wrapper mode

[pboguslawski]

Is it currently possible to define custom content-type header value for success and error responses in place of default application/json; charset=utf-8 for json responses sent from given using given r where

r := chirouter.NewWrapper(chi.NewRouter())

Something similar to https://github.com/swaggest/rest/blob/v0.2.25/_examples/advanced/router.go#L98 avaliable "in github.com/swaggest/rest/web mode".

It is possible to do for SuccessfulResponseContentType, but there is no control yet for error content type.

// Router mode.
	r := chirouter.NewWrapper(chi.NewRouter())
	r.Method(http.MethodPost, "/foo", nethttp.SuccessfulResponseContentType(fooUsecase(),"foo/bar")))

// Same with web.Service.
	s := web.DefaultService()
	s.Post("/foo", fooUsecase(), nethttp.SuccessfulResponseContentType("foo/bar"))
