Provide a Docker option to run the site locally on you machine

[nickebbitt]

I prefer not to install/manage Ruby versions and their dependencies on my Mac and keep them safely contained in a Docker container.

If you have Docker installed on you machines then with a simple docker-compose.yaml file in the project

version: '3'

services:
  jekyll:
    image: bretfisher/jekyll-serve
    volumes:
      - .:/site
    ports:
      - '4000:4000'

You can spin up the site locally with

docker-compose up

Without needing to install Ruby and manage it.

Note: there are various Docker images that help you do this, I picked bretfisher/jekyll-serve at random from a quick Google search but if open to this I can review and choose a good candidate image to provide this feature.
