chore: demonstrate missing logs in kuttl test

[sweb]

Description

Demonstrates missing logs (both streaming while running and after task finishes) in kuttl smoke test.

To reproduce:

./scripts/run-tests --skip-release --parallel 1 --skip-delete \
  --namespace smoke-demo-2 \
  --test smoke_airflow-3.2.2_openshift-false_executor-celery

This will fail. You can also portforward onto the webserver, check the successful dags - the tasks don't have logs and instead state:

Log file not found on worker 'airflow-worker-default-0.airflow-worker-default-headless.smoke-demo-2.svc.cluster.local'...

In order to fix it, add the following envOverride to webserver, celeryExecutors, schedulers and dagProcessors in 40-install-airflow-cluster.yaml.j2:

    envOverrides:
      AIRFLOW__LOGGING__BASE_LOG_FOLDER: "/stackable/log/airflow"

Run the test again, now it passes and you see logs in the UI.
