Wrong response schema for "GET .../files" with "application/zip"

[uniqueg]

While looking at the specs for this response to #247, I found the following glitch in the description of response schemas for the GET .../files operation:

"/tools/{id}/versions/{version_id}/{type}/files":
  get:
    ...
    description: Get a list of objects that contain the relative path and file type.
      The descriptors are intended for use with the
      /tools/{id}/versions/{version_id}/{type}/descriptor/{relative_path}
      endpoint. Returns a zip file of all files when format=zip is specified.
    ...
    responses:
      "200":
        description: The array of File JSON responses.
        content:
          ...
          application/zip:
            schema:
              type: array
              items:
                $ref: "#/components/schemas/ToolFile"

Shouldn't the schema for the application/zip response rather be something like this?

schema:
  type: string
  format: binary

I'll create a PR.
