🚀 Dockerfile for contributing to Jest

Create a DockerFile to run jest.

Motivation

It would be nice to have a option to run Jest with a one-click command instead of having to do any manual setup.

• I'd be happy to create a DockerFile for Jest and matching documentation.

Example

I imagine something along the lines of this (may not be semantically correct):

docker build . /
docker run jest

Pitch

• Make contributing easier & faster by removing manual setup (installing, having to deal with differences between Node versions, yarn, OS differences, etc.)
• Allow all contributors to develop Jest in the exact same environment to reduce the number of platform-specific bugs.
