Docker swarm docker-compose.yml with viewer replication

[PowerBootWS]

I'm not overly skilled at contributing on Github and don't want to make a mess of things, so I'll add this here.

I modified the default docker-compose.yml stack to facilitate deployment on docker swarm using 'docker stack deploy' with replication and rolling updates. It works beautifully when installed on both the docker CLI or Portainer stack. Feel free to add to the repo or share if desired.

# This version was deployed as a STACK in Portainer and therefore does not reference an external .env file.
# If deploying from the docker CLI, be sure to reference the .env file as noted. External ports have been commented out as 
# this version is deployed behind a Cloudflare Tunnel.  See comments.
# Using docker CLI, deploy with: docker stack deploy -c docker-compose.yml typebot
