feat: update sitemap generation for multiple locales

- Refactor generate_sitemap method to support locale
- Add setup_sitemap_config method for configuration
- Implement sitemap generation for default and localized paths

This update enhances the sitemap generation process by supporting
multiple languages. Users can now access a sitemap with language
prefixes, improving SEO and usability for different locales.
Additionally, error handling has been improved to log specific
errors related to locale generation.
