Updated all GitHub Actions from pinned SHA to stable version tags:
- actions/checkout: v4 → v5 (supports Node 24)
- actions/setup-python: v5 with Python 3.13 (explicit version)
- azure/setup-helm: v4 (stable)
- losisin/helm-docs-github-action: v1 (latest)
- helm/chart-testing-action: v2 (stable)
- DavidAnson/markdownlint-cli2-action: v16 → v18 (latest)
Changed from SHA pinning to semantic version tags for better
compatibility with act and easier maintenance. All versions verified
for 2025.
Tested with act dry-run - all steps succeed.
