After the upgrade, redis can no longer be found:

Error -2 connecting to open-webui-redis:6379. Name or service not known.

That's right, because now there is only:

❯ k get services
NAME                        TYPE        CLUSTER-IP    EXTERNAL-IP   PORT(S)    AGE
open-webui                  ClusterIP   10.0.13.211   <none>        80/TCP     118d
open-webui-redis-headless   ClusterIP   None          <none>        6379/TCP   118d

Sorry about that @mrclrchtr, didn't think about the impact on existing clusters when I merged that. I need to also address the use of the Bitnami chart (https://github.com/open-webui/helm-charts/issues/270) next week, so I'll figure out the best way to work a fix in for this as well.

Due to the removal of Redis cluster as a chart dependency, leaving this one unresolved.
