✨ feat(core): export data folder for direct free email domains import

Add data export to @gouvfr-lasuite/proconnect.core package to allow
direct import of most-used-free-email-domains array for external tools
like hyyypertool that need the raw data list.

Changes:
- Add src/data/index.ts barrel export for all data arrays
- Update package.json exports to include ./data path with proper types
- Enhanced README with comprehensive usage examples
- Detailed changeset documentation with French descriptions

Usage:
```typescript
import { mostUsedFreeEmailDomains } from "@gouvfr-lasuite/proconnect.core/data";
```

This resolves migration debt and centralizes free email domain management.
