doc: Update info on information schema usage tables
Commit f40c6969d0 added the information schema usage tables but added
documentation that they did not fully work yet. Commit e717a9a18b
then added SQL-standard function bodies, which made the information
schema views fully functional, but it neglected to update the
documentation. This is now done here.
