ForumTopic object missing when `message_reaction`

[foremtehan]

there's no ForumTopic object in message_reaction update.

The update is kept as small as possible, but the topic's message_thread_id present in the Message object may be added there in the future.

i think it's the time to add message_thread_id to the message_reaction since the forum feature allowed in private chat.

message_thread_id can be uniquely identified by the provided message_id. This is hardly different from any other information about the message.
