Warning when using kustomize v5

[khmjp]

Describe the bug

When using kustomize v5, the following warning message appeared.

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

To Reproduce
Steps to reproduce the behavior:

1. Install kubectl (kustomize v5.0.1).

% curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/darwin/amd64/kubectl"
% chmod 755 kubectl
% ./kubectl version --short --client
Flag --short has been deprecated, and will be removed in the future. The --short output will become the default.
Client Version: v1.27.3
Kustomize Version: v5.0.1

2. Make manifests using kustomize, then see Warning.

% ./kubectl kustomize manifests/base/ > /dev/null
# Warning: 'patchesStrategicMerge' is deprecated. Please use 'patches' instead. Run 'kustomize edit fix' to update your Kustomization automatically.

Expected behavior
No Warning.
