"Response That Returns a File" example for base64 uses format: byte

[Akhlys]

On the Describing Responses page, section "Response That Returns a File", the text mentions "OpenAPI 3.0 defines file input/output content as type: string with format: binary or format: base64". In the code example for the base64 variant meanwhile is this:

   paths:
      /users/me:
        get:
          summary: Returns user information
          responses:
            '200':
              description: A JSON object containing user name and avatar
              content:
                application/json:
                  schema:
                    type: object
                    properties:
                      username:
                        type: string
                      avatar:          # <-- image embedded into JSON
                        type: string
                        format: byte ### ISSUE ###
                        description: Base64-encoded contents of the avatar image

Maybe I'm mistaken, but pretty sure that should be "format: base64" there.
