Update readme_translator.py (#768)

1. Add Logging: Instead of using print statements for errors, we can use
the logging module for better error tracking.

2. Refactor Code: Break down the translate_segment function into smaller
functions for clarity.

3. Add Type Hints: Improve type hints for better code understanding.

4. Handle Empty Translations: Add a check to handle cases where the
translation might be empty.

5. Use Context Manager for File Operations: Ensure files are properly
closed after operations.

> [!IMPORTANT]
> Enhance `readme_translator.py` with logging, refactoring, type hints,
improved error handling, and better file management.
> 
>   - **Logging**:
> - Replace print statements with logging in `translate_sub_segment()`
and `main()` for error tracking and process updates.
>   - **Refactoring**:
> - Break down `translate_segment()` into smaller functions:
`is_html_tag()`, `is_special_character()`, and
`translate_sub_segment()`.
>   - **Type Hints**:
>     - Add type hints to functions for better code understanding.
>   - **Error Handling**:
> - Add check in `translate_sub_segment()` to handle empty translations.
>   - **File Management**:
> - Use context manager in `save_translated_readme()` to ensure files
are closed properly.
