`/dev/ttyACM0` not accessible inside docker container when running Docker rootless

[ChocolateLoverRaj]

I can access /dev/ttyACM0 without sudo because I am in the dialout group. I can run make qemu and it runs Docker rootless. However, if I do make qemu, the program inside the Docker container cannot access /dev/ttyACM0. I think something about the Docker container has to be changed to fix this.
