Description next to $ref gets removed

[JeroenVanOort]

I'm working with an OpenAPI spec like this:

responses:
        200:
          $ref: '#/components/responses/UserResponse'
          description: The updated user.

I use this project to resolve references to external files and to convert to JSON. While doing so, I saw that the description is dropped. The result is like this:

responses:
        200:
          $ref: '#/components/responses/UserResponse'

I know that before, no siblings of $ref were allowed. In 3.1 however, some (like description and summary) are. It would be nice to have support for that in this project.
