Create a github workflow to run RefApp 3.x E2E tests in a dockerized environment

We need to make the tests repeatable despite data mutations. Ideally, the tests would run against a dockerized server and dockerized database where the data is in the image/container itself, such that any changes are lost each time a new container is spun up. Open to other suggestions though. The QA team appears to be doing something like that for the 2.x tests. They have this github workflow https://github.com/openmrs/openmrs-contrib-qaframework/blob/master/.github/workflows/qa.yml, which runs
docker-compose -f docker/docker-compose-refqa.yml up -d
See docker-compose-refqa.yml.
