Greptile Summary

This PR bumps the Helm chart version from 0.3.140 to 0.4.0, releasing recent chart improvements. Since the last chart version, two notable changes were merged: support for secretRef and configMapRef on ServiceContext (#3232), and explicit delete steps for custom stacks (#3226). The version bump follows semantic versioning with a minor version increase, which is appropriate given the addition of new features to the chart templates.

Confidence Score: 5/5

• This PR is safe to merge with no risk
• The change is a straightforward version bump in a Helm chart metadata file with no logic changes. The version increment from 0.3.140 to 0.4.0 follows semantic versioning conventions and accurately represents a minor version bump for new features added to the chart since the last release.
• No files require special attention
