Add Docker notebook tests

[garrison]

The goal here is to test the docker-compose workflow once a week. My plan is to not have the test run upon every PR, unless that PR touches the Dockerfile or docker-compose.yml. In general, if all tests pass in CI, they should pass in Docker too. However, I also think that testing once a week inside Docker as a sanity check will help us make sure the Docker setup is not broken for long, if/when it does break (ahem, #112). If we wanted more frequent testing, we could make it happen daily instead, but then I feel we might be more distracted by intermittent failures than it is worth.

Action items

• Merge Install *all* notebook dependencies in the Dockerfile #112 to fix this workflow
• Remove all triggers except the weekly cron trigger; add triggers on the Docker-relevant files.

Would there be any benefit of running this on both ubuntu and windows, due to some of the hardware architecture snafus we've run into?

I suspect not. The Windows test runners will still have the same hardware as the Ubuntu ones. It'd be nice if we could test on an M1 Mac, but that is not available, and as long as we have the line added in #71 we should be good.
