Little typo: use a right path

The sample composer.json actually sets the bin directory to just bin, rather than vendor/bin (See https://behat-drupal-extension.readthedocs.org/en/3.1/localinstall.html), so this is still in keeping with the current docs. I'm inclined to leave it at just bin for the time being.

I saw it, but I concentrated only the README.md (See https://github.com/jhedstrom/drupalextension and try those steps), and I could not find how I change the bin directory when I use CLI. I worked harder, and I found it. :)

What do you think this pull request?

Ah, you're right. For the README, I think this change makes sense since it makes no reference to changing the bin directory. Thanks!
