We switched to 1.25.1 with v1.34-go1.25-bullseye as part of https://github.com/kubernetes/release/pull/4119. Do we want to streamline everything and move to that version for the other images as well?

[dims]

#4119 was closed in favor of https://github.com/kubernetes/release/pull/4119

So new kube-cross, go-runner, releng-ci image updates are out there now.

image promotion for go-runner image is in https://github.com/kubernetes/k8s.io/pull/8511

distroless-iptables image update: https://github.com/kubernetes/release/pull/4128 image promotion: https://github.com/kubernetes/k8s.io/pull/8516
