Documentation should reference more recent Docker Compose command #47

The current documentation states references docker-compose up when it should use docker compose up instead. More details here.

The text to be changed is in the Preparing to Build the Application section of the README.adoc:

You can now run docker-compose up to start the RabbitMQ service. Now you should have an external RabbitMQ server that is ready to accept requests.

Should instead be:

You can now run docker compose up to start the RabbitMQ service. Now you should have an external RabbitMQ server that is ready to accept requests.
