Cut-over to patchdemo-k8s
Do not merge until go-live!
Updates patchdemo-k8s configuration to serve out of patchdemo.wmcloud.org
- Updates values.yaml to set the default ingress.hostname
- Update .gitlab-ci.yml to explictly set the ingress.hostname
These changes are redundant (you'd only really need to change one) but both were changed for completeness.
Bug: T370076
Closes T370076
