Incorrect return type specified in the documentation

Please answer these questions before submitting your issue. Thanks!

1. What version of pyTelegramBotAPI are you using?
   4.10.0
2. What OS are you using?
   Both Linux/Windows 10
3. What version of python are you using?
   Python 3.9.0

The method telebot.TeleBot.copy_message has wrong type of return data specified in the documentation:

:return: On success, the sent Message is returned.
:rtype: :class:`telebot.types.Message`

In fact this method returns types.MessageID that can be seen at the beginning of the method declaration.

It's also interesting why this method can't return telebot.types.Message as all similar methods (like send_message, forward_message) do.

1. Confirm. Please, make the request with description fix.
2. Your question have reason. But this is the behaviour of Telegram Bot API: https://core.telegram.org/bots/api#copymessage
