Add instructions to setup minIO, RabbitMQ, Postgres in application.properties

[antoinemzs]

I new feedback from today:
Even for the installation part, the docs only mention cloning, editing application.properties and running java -jar file.jar . However, we also need to setup minIO, RabbitMQ, Postgres, and then add all these details into the application.properties . This should be included in the documentation

So we need to improv the documentation on the installation part.
