Migrate tests from behave to taiko
See https://open.greenhost.net/openappstack/openappstack/-/merge_requests/413
We currently have Behave tests (basically python's Gherkin), but the behave-webdriver does not function very well and has been deprecated. That's why we would like to move to Taiko. Because it's javascript-based it also seems to function a bit better with modern websites
