### Describe the solution you'd like

When you return `TypedResults.Problem` from an API you are made to conform to structuring your errors with
a `IDictionary`

This uses the underlying type of [ValidationProblemDetails](https://github.com/dotnet/aspnetcore/blob/3f1acb59718cadf111a0a796681e3d3509bb3381/src/Mvc/Mvc.Core/src/ValidationProblemDetails.cs)

The resulting JSON like this:

```
{
"type": "https://tools.ietf.org/html/rfc9110#section-15.5.1",
"title": "One or more validation errors occurred.",
"status": 400,
"errors": {
"targetLocation": [
"Target location must be a 13-digit GLN",
],
"deliveryDate": [
"Delivery date must be at least two days in the future"
]
}
}

```

Seeing as the structure is enforced on one end it would make sense to have functionality built in to deserialize it on the receiving end, rather than each developer rolling their own implementation.

Currently I have to check the content headers media type for `application/problem+json` and deserialize it.

e.g.
```
if (ResponseMessage.Content.Headers.ContentType?.MediaType is "application/problem+json")
{
// ReadFromJsonAsync & System.Text.Json does not work for me - haven't looked into why
var errors = JsonConvert.DeserializeObject(jsonString);
}
```

It would be nice to have something to do this already, as all the information is there and you have the classes already. If it's too complicated to bake this into the response object perhaps a static class similar to `TypedResults` for retrieving the response.
