Proposal - M series Macs require dedicated docker image

[th3f001]

Rationale:

• on M series Macs, arch should be set to linux/arm64 to avoid emulation and hence performance degradation in docker

• linux/arm64 still don't have google-stable packages, hence
  - docker file should switch to chromium installation as chromium for arm64 is indeed available
  - all reference to google-chrome browser in python code should be changed to point to chromium

• in order to avoid race condition on VNC port usage
  - websocket port and VNC port should be changed to 6081 and 5901 (or any other values other than the default ones)
  - since the container needs to start 3 different services (supervisor.d, VNC and noVNC with websockify) but docker supports only 1 CMD run, it's better to invoke ENTRYPOINT ["/entrypoint.sh"] with a shell script that does that

In attchment, dockerfile, docker-compose.yml and entrypoint.sh files purposely amended.

Dockerfile.txt

docker-compose.yml.txt

entrypoint.sh.txt

Please notice that the resulting container will work but the python app won't since this is still expecting google-chrome.

Thanks for your precious work and congrats for the project.

I've created a PR #154 implementing the suggested changes including ARM64 support, Chromium switch, and port conflict fixes. Looking forward to review and feedback.
