Additional API Compatibility Changes

To support the Helm v3 → v4 upgrade, the following source code changes were made alongside the dependency update:

• pkg/sign/kmspgp.go: Updated OpenPGP imports from golang.org/x/crypto/openpgp to github.com/ProtonMail/go-crypto/openpgp (including armor and packet sub-packages), as Helm v4 migrated to the ProtonMail fork.

• pkg/sign/helm.go: Updated to use Helm v4's new ClearSign(archiveData []byte, filename string, metadataBytes []byte) API. In v3, ClearSign accepted a single chart file path and handled I/O internally; in v4, the caller is responsible for reading the archive bytes and providing the chart metadata YAML. The updated code reads the chart archive, loads it via loader.LoadFile to extract the chart metadata, marshals the metadata to YAML, and passes all three arguments to ClearSign.

Hi @renovate[bot]. Thanks for your PR.

I'm waiting for a cert-manager member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

@copilot, can you suggest additional changes to this PR to allow upgrading from Helm v3 to v4?

In commit 96596c2, I made the following changes to allow upgrading from Helm v3 to v4:

1. pkg/sign/kmspgp.go: Updated OpenPGP imports from golang.org/x/crypto/openpgp to github.com/ProtonMail/go-crypto/openpgp (and sub-packages), since Helm v4 switched from the former to the latter.

2. pkg/sign/helm.go: Updated to use Helm v4's new ClearSign(archiveData []byte, filename string, metadataBytes []byte) API. In v3, the caller passed a file path and Helm did all the I/O internally; in v4, the caller must read the archive data and extract the chart metadata itself. The updated code reads the chart archive, loads the chart to extract its metadata (via loader.LoadFile), marshals the metadata to YAML, and passes all three arguments to ClearSign.
