[Finder] document array use for locations

The function ``Finder::in()`` accepts a string or array of string for look into multiple locations => https://github.com/symfony/symfony/blob/master/src/Symfony/Component/Finder/Finder.php

The other way described is valid, but shouldn't be recommended/documented.
