The "webui-docker-compose" CI check should fail if the package is impacted by the PR itself in a harmful way
All pull request openQA CI checks suddenly failed in "webui-docker-compose", e.g. see
after https://github.com/os-autoinst/openQA/pull/3987 which itself did not fail any tests.
After https://github.com/os-autoinst/openQA/pull/4033 was reverted and packages in devel:openQA were built in the fixed version then new invocations of checks passed again.
