Closing as part of removing the auto-backport workflow (#469).

This PR was opened by the auto-backport bot, which has been broken since 2026-03-13 and is being deleted. The change here is either not applicable to this repo (upstream release chores, dependency bumps, upstream-only docs) or has already landed here through a manual backport. Upstream changes are now backported per PR by hand using the (backport apache/apisix-ingress-controller#NNNN) convention; if this one is still wanted, open a fresh PR that way.
