Update configuration handling and validation for bot sections

- Enhanced .gitignore to allow test files in the tests/ directory and committed pytest.ini for test discovery.
- Added checks for missing sections in configuration files, specifically for Admin_ACL and Banned_Users, to prevent errors during bot startup.
- Updated generate_website.py and command_manager.py to handle cases where required sections are absent, returning empty lists instead of raising exceptions.
- Introduced optional dependencies for testing in pyproject.toml, ensuring a smoother development experience.
- Improved localization handling in core.py to default to English when the Localization section is missing, enhancing user experience.
