use a default values for the flows setting (#10765)

details: if the `flows` setting is left unset, node-red will default the
files it creates for new flows to match the hostname of the container
it's running under. This hostname is dynamic and changes with a pod
restart. As a result changes made and persisted will be lost.

By defaulting the `flows` value to some static value, we ensure that the
changes will persist between pod restarts (assuming using persistent
storage)
