Subject: [PATCH] feat: add Feishu webhook notification for backups

- Include a webhook URL to send notifications after backups.
- Capture and log the duration and size of the backups.
- Create a new Kubernetes secret for storing the Feishu webhook URL.
- Enhance the backup script to notify users of backup success with details.

This change improves monitoring and user notification of backup events,
allowing for better awareness and response times in case of failure or
success of the backup processes.
