SSH Key API Documentation missing "created_at" in sample return data

The API docs for the users shows sample output for retrieving SSH keys. But they don't show the "created_at" data value or the date time format for that given value.

To test, simply make an API call to GET /user/keys and you'll see the extra data value.

The API should be updated to include the missing information.
