Flexget: Conflict dependency with python-telegram-bot

For the latest release of python-telegram-bot v13.0, they explicitly set the minimum requirement for pytz here to be able to use a new attribute. See related issue here

My docker build stays with python-telegram-bot v12.8 for now, but would be great to handle this by Flexget, e.g. fixing python-telegram-bot version or bump the minimum version of pytz compatible with the latest telegram-bot.

Thanks!
