Adding Docker support.

I wanted to discuss if we should add docker support to the project to make the development experience better, although this project doesn't require many entities, unlike the web editor which needs a Mongo instance.
I can work on this if greenlit by the maintainers.

Per #1452 we will have a new website with new development setup so we won't be considering this at the moment. I also don't think a Docker image will help with the development setup of what is essentially a static website (there are no backends, node.js or otherwise, to the p5.js website).
