[Question] how to update edge-tunnel-nodes

[shyer]

What happened:
we deploy raven-proxy-dns after install yurt-manager, yurthub, raven
https://openyurt.io/zh/docs/next/installation/raven-l7-proxy-prepare/

kubectl apply -f config/setup/raven-proxy-dns.yaml
# tunnel-nodes: "" <- tunnel-nodes overwrite

# update image
kubectl apply -f config/setup/raven-proxy-dns.yaml
# tunnel-nodes: ""  <- tunnel-nodes overwrite again，and last-applied-configuration lost  tunnel-nodes

What you expected to happen:
some way regenerate tunnel-nodes
