Bump k8s.io/kube-openapi to pick up kubernetes/kube-openapi#579 which
moved the last ginkgo/gomega tests to stdlib testing and ran go mod
tidy, removing ginkgo/gomega from kube-openapi's go.mod.
This drops ginkgo/gomega as indirect deps from apimachinery. It also
prunes Masterminds/semver, google/pprof, and golang.org/x/tools from
client-go and other staging modules where they were only needed
through kube-openapi's ginkgo/gomega chain.
Contributes to kubernetes/kubernetes#127888
