text: Title: Missing API endpoints /token/verify/ and token/refresh/ in the documentation
  Body: In the documentation from [ReadTheDocs](https://dj-rest-auth.readthedocs.io/en/latest/api_endpoints.html) the API endpoints **token/verify/** and **token/refresh/ are missing.**
  
  I found these API endpoints in the [urls.py](https://github.com/jazzband/dj-rest-auth/blob/master/dj_rest_auth/urls.py) of the project, they are added to the urlpatterns when REST_USE_JWT is set to True.
