Upgrade kustomize version to v4.5.2

The 3.8.x version constantly errors with go modules:
go install sigs.k8s.io/kustomize/kustomize/[email protected]: sigs.k8s.io/kustomize/kustomize/[email protected]
        The go.mod file for the module providing named packages contains one or
        more exclude directives. It must not contain directives that would cause
        it to be interpreted differently than if it were the main module.

See kubernetes-sigs/kustomize#3618

This is fixed in kubernetes-sigs/kustomize#4387
and kustomize v4.5.2

In the future, once we will switch to operator-sdk 1.22 there will be a
separate script to install kustomize:
