Add kustomize 5.2.1

[Mitsuwa]

What

This Adds kustomize 5.2.1 releases to the toolchains https://github.com/kubernetes-sigs/kustomize/releases/tag/kustomize%2Fv5.2.1

It seems that the kustomize folks have changed the windows builds to be zip files instead of tar.gz is that going to break anything on this newer version?

I also need this pr because the latest version 5.1.0 available in the toolchains does not include arm64 macos, which I am now using

If platforms or toolchains are a new concept for you, we'd encourage reading https://bazel.build/concepts/platforms-intro.

@seh please have a look

Please see commits 53b8911 and c26337c, subsuming the change proposed here to include the latest Helm release as well. That's available via the BCR as version 0.3.6.

I discovered only by way of the BCR pre-submit CI workflows that the kustomize project's recent change to use goreleaser (per kubernetes-sigs/kustomize#5239, addressing kubernetes-sigs/kustomize#5220 and kubernetes-sigs/kustomize#5116) required further adjustment to the repository rule that downloads and allows invoking these released tools.
