feature: add a workflow that publishes images to DockerHub

[irving-caamal]

Description

Fixes #88

Type of Change:

• New Feature

How Has This Been Tested?

1. Published on my fork you can check it here
2. You can also check the images
   2. - frontend
   2. - backend
   2. - bot

Steps before merge:

1. You need to set two secrets on Github Secrets

   • DOCKER_USER (docker hub username)
   • DOCKER_USER (docker hub password)

2. You need to create formica-bot, formica-frontend, formica-backend repositories on DockerHub (this is an opinion, you could set those each docker push)

Ideas

After publishing all images maybe you can set the image for each service of Formica on the docker-compose.yml file, like so:

backend:
		image: formica/formica-$SERVICE
        build: 
            context: ./backend
            dockerfile: dev.Dockerfile
        volumes:
            - ./backend/:/code/
        ports:
            - "8000:8000"
        depends_on:
            - db
