Add JSON serialization for all Telegram Bot API types

Implemented robust JSON parsing and serialization for all Telegram Bot API data structures using nlohmann/json. Each type now includes functions for converting between C++ objects and JSON, supporting nested objects, arrays, and polymorphic types. This enables seamless integration of Telegram data in C++ applications and modernizes the codebase for future API updates.
