[Proposal] Oneliner with docker

[ghost]

Hi @pahen,

Thanks for this awesome project. I wanted to share that I have package Madge into a docker image to run it without installation.

docker run --rm -v "$(pwd):/app" savadenn/madge madge --extensions ts --image dependencies.g.svg --ts-config tsconfig.json ./src

Source are here

I'm not familiar with github CI but I can give it a go. Do you want a try at this ?

I'm not sure what is needed here, maybe add it to README of this repo?
