Code Review

This pull request downgrades the Grafana sidecar image version to 2.0.3 to address a race condition. The change is straightforward and appears correct. The suggestion to include an inline comment explaining the version pinning has been kept as it improves long-term maintainability and does not conflict with any existing rules.
