[Infrastructure] Implement FrontEnd CI/CD pipeline

Implement the FrontEnd pipeline to achieve the following objectives:

• Build the FrontEnd Docker image.
• Push the Docker image to Dockerhub.
• Restart the service (pull and restart).

cc @hugopeixoto before we start building the pipeline we also need to know:

• How to build the Docker image (basic commands)
• Any other resources needed: Docker Compose file, Nginx, env vars, etc.
