Update PengradTelegramBot to improve chat ID retrieval and upgrade Telegram API version

- Refactor chat ID extraction logic into a separate method for clarity and maintainability.
- Handle cases where chat ID may not be accessible, logging a warning when not found.
- Upgrade Telegram Bot API dependency version from 6.2.0 to 7.1.1.
- Adjust BotRequestImpl to accommodate changes in chat ID retrieval logic.
- Make botAtomicReference in App class final for better thread safety.
