Template for Pipenv-based Dockerfile

Delete everything above the dash and the dash itself when making a new repo. Make sure to replace <name> as necessary.

1. Update the README
2. Update the Dockerfile
3. Update the workflow. Note: The first two steps can be done in either order, but it is absolutely necessary to do the third step last.
