Add documentation

[asmataamallah25]

This pull request enhances the project documentation by adding three crucial components:

• Setup Requirements:
  Detailed instructions for setting up the environment to run Canis Major, including specific versions of Java and Docker.

• Troubleshooting Guide:
  Addresses the most common issue: build failure during integration tests.
  Provides a clear, step-by-step solution to resolve the NGSI address problem.
  Includes explanations of commands used in the troubleshooting process.

• Integration tests guide

These additions aim to improve the user experience for new contributors and help current users resolve common issues quickly.

I suggest that you change all this content by the following:

For a docker compose clean, execute the following command:

   sudo docker compose -f docker-compose-env.yaml -f docker-compose-java.yaml down -v

This command deletes all containers, networks, and volumes created on the corresponding compose. It is the normal way to remove resources in a compose. Your steps delete all the containers, volumes, and networks you have created in your machine, including others not related to the deployment of Canis Major.

Actually I see merit in including both options. @flopezag has the best default solution, but @asmataamallah25 's drastic clean-up can also be useful if the machine has other resources running in conflict to Canis Major. Maybe something like this would work.

### Solution 1: Clean the docker compose

For a docker compose clean, execute the following command:

`shell
   sudo docker compose -f docker-compose-env.yaml -f docker-compose-java.yaml down -v
`

This command deletes all containers, networks, and volumes created on the corresponding compose. It is the normal way to remove resources in a compose.

### Solution 2: Remove all docker resources from the machine

Delete all the containers, volumes, and networks you have created in your machine, **including others not related to the deployment of Canis Major.**

For a complete Docker cleanup of all resources:
- Stop all running containers
   ```shell
   sudo docker stop $(sudo docker ps -aq)

• Remove all containers

   sudo docker rm $(sudo docker ps -aq)

• Remove all volumes

   sudo docker volume rm $(sudo docker volume ls -q)

• Remove all custom networks

   sudo docker network prune

Ok then, I suggest to put the two options in the documentation.
