Download kustomize 5.8.2

Introduction
In this release, we implemented refactoring to update dependencies and add new features.
This release adds the kustomize edit add configuration and kustomize edit remove component commands. #6037 #6083
The built-in OpenAPI schema is now loaded from a pre-compiled bundle embedded in the binary. #6190
The schema itself is still based on Kubernetes v1.21.2, so the output of kustomize build is not expected to change. If you notice any difference, please file an issue.
