doc: update the assert module summary

The current wording "This module is used for writing unit tests for your
applications, you can access it with require('assert')." implies that
this module should only be used in development while unit testing.

The article "Error Handling in Node.js" by Joyent
(https://www.joyent.com/developers/node/design/errors) uses the assert
module in an efficient way to validate required function arguments.
