🚀(docker) dockerize frontend dev

Dockerize the frontend development environment
to make it easy to display the frontend
development environment in the browser.

We don't mix it with the command `make run` to
let it kind of optional to run the frontend
in a docker container. We let it optional because
the hot reload doesn't work well in the docker
container. The volume synch make it a bit slower
as well. So, we let the developer decide to run
the frontend in a docker container or not.
