Pull Request Overview

This PR adds missing type annotations to improve code clarity and type checking in the telebot module.

• Updated the add() method signature in InlineKeyboardMarkup to provide type annotations for *args and row_width.
• Specifies that *args should be of type InlineKeyboardButton and makes row_width an Optional[int].

Comments suppressed due to low confidence (1)

telebot/types.py:2895
