Remove dubious warning message from SQL/JSON functions

There was a warning that FORMAT JSON has no effect on json/jsonb
types, which is true, but it's not clear why we should issue a warning
about it.  The SQL standard does not say anything about this, which
should generally govern the behavior here.  So remove it.
