go: finding module for package k8s.io/api/auditregistration/v1alpha1

../../pkg/mod/k8s.io/[email protected]+incompatible/kubernetes/scheme/register.go:26:2: module k8s.io/api@latest found (v0.19.3), but does not contain package k8s.io/api/auditregistration/v1alpha1

原因：k8s.io/client-go 版本不对

解决办法：修改go.mod
