Revert Deployment Engine image tag pin in Helm chart

[brooke-hamilton]

Description

Reverts the Deployment Engine (de) image tag pin in deploy/Chart/values.yaml. The tag was previously pinned to 0.56 for the v0.57.1 patch release. With that release out, the chart should fall back to using the Chart AppVersion as the default tag.

Type of change

• This pull request is a minor refactor, code cleanup, test improvement, or other maintenance task and doesn't change the functionality of Radius (issue link optional).

Pull request overview

Reverts the Helm chart’s temporary pin of the Deployment Engine (de) image tag so the chart again defaults to using a tag derived from the chart AppVersion (via the chart helper logic), consistent with other control-plane components.

Changes:

• Removed the hardcoded de.tag: 0.56 value from deploy/Chart/values.yaml.
• Updated inline comments to reflect the defaulting behavior when de.tag is unset.
