fix(common, metallb-config) change deprecated annotation prefix to m…

…etallb.io (#30405)

**Description**

metallb deprecated the old annotation prefix metallb.universe.tf in
favor of metallb.io. See
[release-notes](https://metallb.universe.tf/release-notes/) and
[pr-2495](metallb/metallb#2495)

This currently leads to warnings in logs for pods using loadbalancer
ips.
