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

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?

Additional information

Start by reproducing the provided Dockerfile and tracing the sourced workspace around micro_ros_setup's create_firmware_ws.sh and build_firmware.sh entry points. Check whether the image can retain and access the built workspace after each Docker RUN step; done means the image builds successfully with the custom subscriber and can execute it from the Docker Compose setup.
