Automatic update of Helm Chart metadata using pipeline

[samidbb]

This pull request enhances the CI workflow for Helm chart versioning and metadata updates. The changes automate updating not just the appVersion, but also the image tag and the chart version in the Helm chart files, ensuring consistency between deployments and version tracking.

This update should enable communication about updates in the Helm Chart for consumers

Helm chart metadata automation:

• The CI script now updates both the appVersion in chart/Chart.yaml and the image tag in chart/values.yaml to the current GitHub run number, ensuring that deployments use the correct image version.
• The chart version in chart/Chart.yaml is automatically incremented (patch version bumped) each run, improving version tracking for Helm releases.
• The commit step now stages both Chart.yaml and values.yaml and uses a more general commit message ("chore(ci): update chart metadata [skip ci]"), reflecting the broader scope of changes.
