Bump Kubernetes to v1.30

[twz123]

Tracking issue for the 1.30 update.

• Bump Go to v1.22
  Kubernetes 1.30 requires Go 1.22+.
  Bump Go to v1.22.0 #4115
• Check compatibility with kube-proxy's nftables backend (KEP-3866)
  (I think it will stay alpha in 1.30) Tracked in Support for kube-proxy nftables backend (KEP-3866) #3842.
• Ship quay.io/k0sproject/kube-proxy:v1.30.0
  k0sproject/image-builder#85
  Maybe it needs the nft binary, see above.
• Check if CNI plugins are up to date
• Check Helm / controller-runtime compatibility
  ⚠ Bump k8s.io/ to v1.30.0-beta.0 kubernetes-sigs/controller-runtime#2693
  🐛 Revert "🌱 Bump github.com/prometheus/client_golang" kubernetes-sigs/controller-runtime#2750
