Revert "Update kubebuilder to the latest working version" (#7632)

Reverts #7629

This was fixed as per the convo in
kubernetes-sigs/controller-runtime#2838. It
looks like the binaries weren't released for the version of Kubernetes
that we were using (they had up until 1.24 but we were using 1.23)

Fixes: #7630
