Automated tests

[alangecker]

people (namely @gabriellpr @antonbsa @MaximKhlobystov ...) have spent quite some work into automated tests for BBB https://github.com/bigbluebutton/bigbluebutton/tree/develop/bigbluebutton-tests

it would be great if we would also use them to verify, that every functionality works within the docker setup.

seems like a lot could simply be copy+pasted, but I'm not familiar with github workflows. maybe someone else would be up for having a look? 🙂

All it would need is a PR which enables running the tests, I can then take care about all the failing ones ;)
