PAPERLESS_REDIS may be set via docker secrets

Best practice is for redis to be at least password protected: https://redis.io/docs/getting-started/.

Paperless uses `Redis.from_url` (https://github.com/paperless-ngx/paperless-ngx/blob/5fe435048bc6eb77f9473afc11588427846456ab/docker/wait-for-redis.py#L24) to establish a connection to redis which already enables us to use username/password, e.g. `redis://username:password@redis:6379`.

The redis connection string therefore is a secret and needs to be able to leverage docker secrets, hence this PR.
