Short code for big integer appears in docs for cols() but not docs for vroom(col_types =)

Let's say this table is the definitive info on available specifications:

https://vroom.r-lib.org/reference/cols.html#details

Does it make sense to duplicate that in the docs for vroom()? If yes, then vroom() needs to gain docs for the I short code for big integer. If no, then the problem goes away.

IMO it should just be a reference.
