Update deployment-operator chart to 0.6.56

Greptile Summary

The PR advances the deployment-operator Helm chart and its default application image tag from 0.6.55 to 0.6.56.

• Keeps the chart version and appVersion synchronized.
• Makes 0.6.56 the default image tag when users do not provide an explicit override.

Confidence Score: 5/5

The PR appears safe to merge because it applies the expected lockstep chart and application version bump without introducing an established failure.

The metadata remains internally consistent, and no evidence indicates that release 0.6.56 needs additional chart changes or references unavailable images.
