feat(charts): add initContainer configuration for TCP checks

- Introduced additional init container configuration in values.yaml for TCP dependency checks.
- Updated comments to ensure clarity and compatibility with helm-docs format.
- Documented new fields including tcpCheck settings, image details, timeout, and resource limits.
