Proactively bump to v0.12.0 to avoid v0.10.0 and v0.11.0, which contain
a regression added by commit
82780d606d.
This commit was later reverted in v0.12.0.
Generated with:
hack/pin-dependency.sh golang.org/x/net v0.12.0 && hack/update-vendor.sh
They contain some nice-to-have improvements (for example, better printing of
errors with gomega/format.Object) but nothing that is critical right now.
"go mod tidy" was run manually in
staging/src/k8s.io/kms/internal/plugins/mock (https://github.com/kubernetes/kubernetes/pull/116613
