Fix docker development set-up (#2102) (!2367) · Merge requests · funkwhale / funkwhale

I'll explain the fixes since it affects multiple files:

api/Dockerfile: py3-cryptography-38.0.3-r0 breaks world[py3-cryptography=38.0.3-r0], so I've simply updated it to r1.
api/Dockerfile: dev-requirements.txt dependencies were not loaded because of an invisible leading character in ln 74-80 (I almost went nuts with this one). So libraries for dev weren't loaded (/bin/sh: grep: not found), hence the modules not found exceptions for factory and debug_toolbar.
docker/nginx/conf.dev: restored location /statifiles block. Otherwise static files wont' load in admin pages
Finally api/funkwhale_api/music/fake_data.py: since the tracks created weren't playable they weren't displayed. create_data method it's not called anywhere in the codebase. Apparently it's only used when setting up local data.
