Changes required to import the movielns DB

[MagnarAr]

When running this docker-compose, it will start the Python notebook and neo4j container. To use the provided movielns.db, make sure that after first running the container, modify the configuration file in the git source root:

<project_root>/neo4j/conf/neo4j.conf
Add following lines:

dbms.active_database=movielns.db
dbms.allow_upgrade=true

And restart the docker container (from the Docker Desktop dashboard or using command line).
