### Body

Currently our telegram integration uses Telegram v13 telegram-bot library. On 1st of Jan 2023 a new, backwards incompatible version of Telegram-bot has been released : https://pypi.org/project/python-telegram-bot/20.0/#history and at least as reported by MyPy and our test suite test failures, Telegram 20 needs some changes to work:

Here is a transition guide that might be helpful. 

Transition guide is here: https://github.com/python-telegram-bot/python-telegram-bot/wiki/Transition-guide-to-Version-20.0

In the meantime we limit telegram to < 20.0.0

    This hook allows you to post messages to Telegram using the telegram python-telegram-bot library.
    The library can be found here: https://github.com/python-telegram-bot/python-telegram-bot
    It accepts both telegram bot API token directly or connection that has telegram bot API token.
    If both supplied, token parameter will be given precedence, otherwise 'password' field in the connection
    from telegram_conn_id will be used.
    chat_id can also be provided in the connection using 'host' field in connection.
    Following is the details of a telegram_connection:
    name: 'telegram-connection-name'
    conn_type: 'http'
    password: 'TELEGRAM_TOKEN'
    host: 'chat_id' (optional)
    Examples:
    .. code-block:: python
        # Create hook
        telegram_hook = TelegramHook(telegram_conn_id="telegram_default")
        # or telegram_hook = TelegramHook(telegram_conn_id='telegram_default', chat_id='-1xxx')
        # or telegram_hook = TelegramHook(token='xxx:xxx', chat_id='-1xxx')
        # Call method from telegram bot client
        telegram_hook.send_message(None, {"text": "message", "chat_id": "-1xxx"})
        # or telegram_hook.send_message(None', {"text": "message"})
    :param telegram_conn_id: connection that optionally has Telegram API token in the password field
    :param token: optional telegram API token
    :param chat_id: optional chat_id of the telegram chat/channel/group
