make --version show the same value inside package.json

The CLI flag "--version" wasn't showing the right version of the package.

It had a hardcoded version number that needed to be changed along with the
one inside package.json and sometime ago people stopped updating it.

This implementation ensures the "--version" flag always report the same
value inside package.json, without any need for manually updating.
