- Removed the `BotUsername` property from `TelegramOptions` and updated the `.env.example` to reflect this change, as the bot's username is now dynamically retrieved via the Bot API. - Introduced `ITelegramBotInfo` to cache the bot's username, improving the handling of deep links in `TelegramEndpoints`. - Updated API documentation to clarify that the deep link is now dependent on the bot's token and its availability through the Bot API, enhancing clarity for developers.
