support for links in JSON:API?

[mqchau]

Hi, in my own backend that implements JSON:API, I use the links as indicated the documentation of JSON:API like this https://jsonapi.org/format/#document-links . I wonder if you guys plan to support it? I'm thinking of something like the @Attr you already did:

@Model()
class Person extends ApplicationRecord {
  static jsonapiType = "people"

  @Link() self: string
}

If you guys think it's good idea to support it then I can attempt a PR.
