A cache repo containing pre-built Helm binaries, used as a fallback download source for Magda's CI/CD pipeline when the official distribution endpoint is temporarily unreachable.
Binaries are attached as assets to versioned GitHub Releases (e.g. v3.13.2),
matching the naming convention used by the official Helm distribution:
helm-v<version>-linux-<arch>.tar.gz
Checksums (sha256sum) for each asset are listed on the corresponding
release page.
