Some fixes for the docker build.

- Messed with readme.
- They needed to be `.env`, not `env`.
- Leaving the nginx file there, but extracting it out of the main setup. Ppl might use apache, or none at all.
- Docker 3.3 doesn't work with the DB health check unfortunately, so I changed that back to 2.4.
- Changed the env in the docker folder so it doesn't need to be edited, someone could just pull this and start it up if they just wanna test it.
