[Feature-Request] Add new favorites over Telegram-Menu

[Tqnsls]

Hi Henning,
would it be possible to add a new menu-item to add more favorite items?
I am thinking of something like /add_favorite 123456, (which is the item_id) almost like the /mute 5 to mute it for 5 days.
In a latest state maybe the full URL could be used, idk.

I am trying to define a new command in the telegram.py. Pls notice I am not really a python dev. I already imported the tgtg_client but the latest error which I can not resolve (as I do not know how to load the tokens), was "You must provide at least email or access_token, refresh_token and user_id".
Maybe you can see this as an inspiration to extend the telegram.py or give me a hint how I could do it myself and merge it to the project.
I happily will share the stuff I copy-pasted til now :)

Hello, this exists already in the project (ether with using /addfavorites or by just sharing the item link with the bot). The issue is just that there wasn't a new prebuilt binary release after the changes were added. I don't know which platform you want to use the bot on but if you use any other installation method except prebuild binary the feature is included.

Ah, I just found your PR #386 :)
Tested in a venv and it worked, I hope @Der-Henning will build a new release soon :)
