Docs incorrect - 403 response from currently-playing returning TEXT instead of JSON

[fergusJ]

The docs at get-the-users-currently-playing-track state that a 403 response should return an object containing: status (int), message (str).

I am getting: "Check settings on developer.spotify.com/dashboard, the user may not be registered."
In plaintext.

If this is expected, the docs should be updated to say this.
