Instead of maintaining the version number in 3 separate files
(baileys-version.json, index.ts, generics.ts), this change makes
baileys-version.json the single source of truth. Other files now
import the version from this JSON file.
This follows the DRY principle and reduces:
- Risk of version inconsistency across files
- Maintenance burden (only 1 file to update)
- PR diff size (3 files → 1 file for version updates)
- Merge conflict probability
Addresses inefficiency found in Baileys PR #2269.
