[release-branch.go1.22] cmd/go: fix go list -u -m all with too new retractions dependency

Previously, go would not report retractions of dependencies that have a
newer version of Go. With this change, we will still display retractions despite a version difference when go list -u -m is used.

For: #66403
Fixes: #68052
