templates: 'patchesStrategicMerge' is deprecated

/kind feature

Describe the solution you'd like

While running make templates, we can see the following output:

# Warning: 'patchesStrategicMerge' is deprecated. Please use 'patches' instead. Run 'kustomize edit fix' to update your Kustomization automatically.

Can be observed in the CI output too.

Anything else you would like to add:

This comes from the new Kustomize version being used: https://github.com/kubernetes-sigs/kustomize/releases/tag/kustomize%2Fv5.0.0

We are deprecating the following kustomization fields. These fields will never be removed from the kustomize.config.k8s.io/v1beta1 Kustomization API, but they will not be included in the kustomize.config.k8s.io/v1 Kustomization API. When Kustomization v1 is available, we will announce the deprecation of the v1beta1 version. There will be at least two releases between deprecation and removal of Kustomization v1beta1 support from the kustomize CLI, and removal itself will happen in a future major version bump:

• patchesStrategicMerge. Please use patches instead
