Use the latest avaialble "kustomize" release

Introduce _kustomize_ version 5.1.0 and Helm version 3.12.1, making
each of them the new default version. Note that this latest version of
_kustomize_ lacks support for the ARM64 architecture for both macOS
and Windows, per kubernetes-sigs/kustomize#5220.

Skip _kustomize_ version 5.0.2 due to its change in handling
downloaded Helm charts, and instead move past it to version 5.0.3.

Broaden support for the Helm toolchain

Make more versions of the Helm toolchain available for ARM64 machines
running macOS, and automate the publication of GitHub releases.
