Update Sphinx config for better doc rendering 📚

- Changed `source_suffix` to dictionary format for explicit mapping.
- Set documentation language to English in `conf.py`.
- Updated `intersphinx_mapping` for clearer reference links.

These adjustments improve the clarity and flexibility of the documentation setup, ensuring a more consistent and user-friendly experience.
