By default empty allowed_updates allows bot to receive all update types except chat_member (default).
In many cases chat_member is preferable along with other update types.
We can provide pre-populated array of all possible update types out of the box.

UpdateType[] AllUpdateTypes = Enum.GetValues<UpdateType>()[1..];
