Important Update to docker-compose file

Update docker-compose file

We have recently made some changes to NearBeach's docker deployment process. One of these changes is to implement cron jobs within the docker container. This will be used for the scheduler (coming soon).

The other change is we have removed the "command" section within the docker compose file. Please see our "self-hosting" page for reference.

Remember, before implementing the change, backup both database and environment.
