[stable/airflow] Airflow connections values fix (#16159)

* [stable/airflow] Hotfix for `connections` default value

* connections should be a list by default, to avoid error trying overwrite map with list when passing actual list with connections. See: https://github.com/helm/charts/pull/10317#pullrequestreview-194739611
