Homogenize example and remove reference to borsh-js

The current examples differ on what they encode / decode, but more
importantly, they refer to a `borsh-js` package that does not exist

I have modified the dependencies to use the actual Borsh encoding, and
homogenized the code so they execute exactly the same code
