feat(whatsapp): implement fetchLatestWaWebVersion utility and update version fetching logic

- Added a new utility function `fetchLatestWaWebVersion` to retrieve the latest WhatsApp Web version.
- Updated the Baileys service and router to utilize the new function instead of the deprecated `fetchLatestBaileysVersion`, ensuring accurate version information is fetched for WhatsApp integration.
- This change enhances the reliability of version management in the application.
