fix(release): pass Helm version to registration

[svvarom]

Summary

Forward the already-resolved Helm chart version in the stable release-registration payload whenever Helm is selected.

Why

A stable Helm-only release can use SemVer build metadata for a chart correction while retaining the application release version. The registration consumer needs the exact chart version instead of assuming both versions are identical.

Non-Helm releases and all existing build, staging, polling, and deployment behavior remain unchanged.

Validation

• actionlint .github/workflows/release.yaml
• git diff --check

Rollout

Merge after the registration consumer accepts the optional helm_version field.

Summary by CodeRabbit

• Improvements
  • Release registration now includes the Helm version when Helm artifacts are part of a release.
  • Improved release metadata accuracy for Helm-based releases.
