[Local] Bring the mongodb up as a container

### Description
After https://github.com/DeKal/illuminati/issues/242, we may bring the mongodb up as a container.
Currently, we need to setup locally our mongo db on local to be able to run it. It’s quite complex for some beginners. Therefore we need to bring the thing in docker too.
1) Create a Dockerfile for mongoDB
2) write a script, or `docker compose` to bring up the mongodb, setting up with dummy data
3) Bring up our app cointainer, connecting with the DB
