Cheermote fragments as possible for EventSub chat.notification topic

[theca11]

Brief description
The payload reference for the Channel Chat Notification Event includes cheermote objects as a possible message fragment. However, cheers go through chat.message events not chat.notification ones, so it doesn't feel possible for them to be non-null.

Expected documentation
For Channel Chat Notification Event:

• Remove cheermote as a possible value for the type field
• Document the cheermote object field to be always null for this topic
