feat: ✨ general-purpose exception class

[Erlend Ellefsen (erlendellefsen)]

• Added JsonApiHttpException - a general-purpose exception class that accepts any HTTP status code

throw new JsonApiHttpException(406, "The requested media type is not supported");

{
  "errors": [
    {
      "status": "406",
      "title": "Not Acceptable",
      "detail": "The requested media type is not supported"
    }
  ]
}
