Summary

This PR updates the azure/setup-helm GitHub Action from v4 to v5 in two workflow files (.github/workflows/ci.yml and .github/workflows/release-please.yml). Verdict: Ready to approve — this is a straightforward dependency update with no breaking changes affecting the current usage pattern.

Research notes

I reviewed the official azure/setup-helm repository and its CHANGELOG:

• v5.0.0 release date: March 23, 2026
• Primary change: Node.js runtime updated from node20 to node24 (PR #259)
• Additional changes: Multiple dependency bumps including undici, minimatch, js-yaml, glob, @actions/http-client (security and maintenance updates)
• No breaking API changes: The action's inputs remain unchanged; the version parameter continues to work as before

The current usage pattern (uses: azure/setup-helm@v5 with version: "3.13.0") is valid and follows the documented usage in the action's README.

Suggested next steps

1. Merge this PR — the update is safe and includes beneficial security patches.
2. (Optional follow-up) Consider pinning the action to a specific version tag (e.g., @v5.0.0) instead of the floating @v5 major-version tag if you want stricter reproducibility. This is a common practice for security-conscious workflows, though using major-version tags is also widely accepted when the action maintainer follows semantic versioning.

General findings

Observation only (not a blocker): Both workflows specify Helm version 3.13.0, which is older than the action's fallback default (currently 3.18.3 per the README). The action will attempt to fetch the requested version, but if that fails, it will silently use the fallback. This is pre-existing behavior and not introduced by this PR, but worth being aware of in case of unexpected Helm version mismatches during CI runs.
