Refactor the image-update-and-release workflow to correctly handle Chart.yaml updates:
Changes:
- Add chart_version_update_needed flag in Update values.yaml step
- Compares WordPress version before/after update
- Only sets flag=true if WordPress version actually changed
- Modify Increment chart version step to run only when chart_version_update_needed=true
- Implement proper suffix handling for versions like 6.9.3-a, 6.9.3-b, etc
- Support upgrading base version without suffix to add -a suffix
- Update Commit and push changes step
- Always add values.yaml
- Only add Chart.yaml if WordPress version was updated
- Update Create Helm package and Create release tag steps
- Only run if Chart.yaml was updated (chart_version_update_needed=true)
- Update Summary step to show whether Chart.yaml was updated
This prevents Chart.yaml from being updated when only Nginx or other images change,
avoiding version number regression issues (e.g., 6.9.3 -> 6.9.4 when only Nginx updated).
