fix: initContainer enabled properties not define in template

[drivebyer]

• Bumped version and appVersion for redis, redis-cluster, redis-replication, and redis-sentinel charts to 0.16.4, 0.16.4, 0.16.6, and 0.16.8 respectively.
• Enhanced initContainer properties in templates to include the 'enabled' field for better configuration management.

This update ensures consistency across the Redis charts and improves template rendering.
