Add Zend\ServiceManager v3 compatibility

[mpalourdio]

Hello,
I wanted to give this skeleton a try. So I just did composer create-project zendframework/zend-expressive-skeleton but directly ran into the following error after install :

Fatal error: Uncaught TypeError: Argument 1 passed to Zend\ServiceManager\ServiceManager::__construct() must be of the type array, object given

I had chosen : FastRoute, Zend\ServiceManager and Twig as dependencies.

It appears that the installer made me download Zend\ServiceManager v3 as dependency. This PR fixes the config file to be compliant with v3, whose constructor expects an array to be injected.

I see the tests fail. I just tried a git clone && composer install and Zend\ServiceManager v 2.7.3 is downloaded as a dependency. I suppose that one of the packages retrieved by the interactive installer forces the v3 dependency.

Here is my generated composer.json

The way to make it work with both v2 and v3 is to create a Zend\ServiceManager\Config instance with the dependency configuration, and then $config->configure($container), if you want to update this PR to work with either version.

I'm really not sure how you were getting the 3.0 version (the constraints should never install it), nor why an update is downgrading versions to pre-1.0 tags. Honestly, I suspect a subtle composer issue or stale composer cache.

Thanks for you suggestion, I have updated this PR.
