Refactor language switcher and enhance site routing

Renamed 'LanguageDropdownSwitcher' to 'LanguageSelector' for better representation of the component's functionality. Removed unnecessary dependencies and optimized function declarations. Updated site routing to include new pages like 'contact', 'terms-of-service', and 'privacy-policy'. Also made adjustments for multi-language support, providing better user experience.
