updating dockerfile to include api server (#14)

The existing dockerfile only ran the frontend React app. It needed to
have the Python API included.

- Switched from alpine to ubuntu because alpine was giving me grief
about installing python requirements, but this required following the
node people's cumbersome instructions for how to get an even remotely
up-to-date version of node because ubuntu defaults to v12 😱
- Created a shell script per docker recommendations to start the
frontend and backend servers (took some time to track down that I now
need to provide the aught host param to vite to expose the web interface
outside the container)
