Pull request overview
This pull request adds support for configuring Istio revision values in the sn-platform and sn-platform-slim Helm charts. The revision field allows users to specify which Istio control plane revision to use for sidecar injection, which is essential for supporting Istio canary upgrades and multi-revision deployments.
Changes:
- Added a new
revisionfield to theistioconfiguration section in both charts' values.yaml files - Applied the revision configuration to broker, bookkeeper, and zookeeper cluster templates where Istio is enabled
- Maintained consistency with existing conditional patterns for optional Istio features

The comment states that the revision will be applied to "broker, bookkeeper, and zookeeper components", but the proxy component also has an istio configuration section and would benefit from revision support for consistency. Consider updating the proxy-cluster.yaml template to include the revision field in its istio section, and update this comment to reflect all components that support the revision field.
