Dockerfile can't be build if I add personal micro-ros subscriber to micro-ROS-demos

Personne n'a encore pris cette issue.

## Issue template

- Hardware description: Ubuntu 22.04
- RTOS:
- Installation type: micro_ros_setup
- Version or commit hash: humble

#### Steps to reproduce the issue
Hey, my goal is to create a Docker container where everything is set up, and I can directly execute my own subscriber from a docker compose file and don't have to run commands in the terminal.
My plan was to copy my publisher after I ran `ros2 run micro_ros_setup create_firmware_ws.sh host` into the workspace but afterwords when I run `ros2 run micro_ros_setup build_firmware.sh` it throws an error because micro_ros_setup can no longer be found ( I think this is because they are in different layers of the image and not have access to each other).

Any ideas how I can solve my issues?

#### Expected behavior

#### Actual behavior

#### Additional information

Commencez par reproduire le Dockerfile fourni et retracez le workspace chargé autour des points d’entrée create_firmware_ws.sh et build_firmware.sh de micro_ros_setup. Vérifiez si l’image peut conserver le workspace construit et y accéder après chaque étape Docker RUN ; le travail est terminé lorsque l’image se construit correctement avec le subscriber personnalisé et peut l’exécuter depuis la configuration Docker Compose.
