feat: add makeWASocketAutoVersion for automatic version fetching

Adds a new async function that automatically fetches the latest
WhatsApp Web version from web.whatsapp.com before connecting.

Usage:
```typescript
// Option 1: Auto-fetch version (recommended)
const sock = await makeWASocketAutoVersion({ auth: state })

// Option 2: Manual version (existing behavior)
const sock = makeWASocket({ auth: state })
```

Benefits:
- No need to update library for version changes
- Automatic fallback to bundled version if fetch fails
- Logged warnings when using fallback
