CI with GitHub Actions

The runner image of ubuntu-latest has Chrome and a matching chromedriver; vendor/bin/bdi detect drivers makes sure. Run the End-to-End tests in a job of their own, upload the screenshots when it fails, and add a job summary that links to them (docs/examples/end-to-end.yml):

bdi is dbrekelmans/bdi; add it with composer require --dev dbrekelmans/bdi. PANTHER_NO_SANDBOX=1 is needed on the GitHub runners.
