Restrict some cases in parsing numerics in jsonpath

Jsonpath now accepts integers with leading zeroes and floats starting with
a dot.  However, SQL standard requires to follow JSON specification, which
doesn't allow none of these cases.  Our json[b] datatypes also restrict that.
So, restrict it in jsonpath altogether.
