Add more examples of data types in documentation


When trying to sift through all the documented data types with “sign in with coinbase,” I understand there are nuances that cannot possibly be documented, however, it would be very nice if you had a sample of each data type that could come out.

For example, there’s 2 different schemas for send, and 2 for receive, etc., but they are not documented anywhere, and you just have to assume the data will properly be ingested.
