blog: Fix Decoding arbitrary data example

The example on the blog post json-and-go describes decoding arbitrary 
data, but instead of switching on the default concrete type for 
numbers - float64, it looks for int, making it print:
is of a type I don't know how to handle.

This change looks for float64 instead of int.
