jellyfin-ha: pull image from artifactapi docker-internal registry

The build repo's release pipeline pushes the runtime image to the
artifactapi local docker registry, not Gitea. Point the StatefulSet at
artifactapi.k8s.syd1.au.unkin.net/docker-internal/jellyfin-ha:v0.1.0 so
the deploy pulls the image the build actually produces. Pull is anonymous
in-cluster (no imagePullSecret), matching every other docker-internal
workload in the estate (encapi, pdbmux, bind-operator, cephrgw, age-api).
