Change to suggest django-storages-redux in docs

The original django-storages is a dead project that haven't seen any
updates since early 2014, including a lot of unmerged pull requests.
Django-storages-redux is a fork well accepted, under active
development and python 3 support. We should link to it instead of the
old one.
