Correct ZendViewRendererFactory feature description

[shadyan]

See here:
https://docs.zendframework.com/zend-expressive/v3/features/container/factories/#zendviewrendererfactory

Says "no additional services are required", but then lists a dependency.

I made a separate pull request for this since this case might be a bit more complex. My understanding is that the actual dependency is the UrlHelper.
The ZendViewRendererFactory comments added some more confusion:

Requires the Zend\Expressive\Router\RouterInterface service (for creating the UrlHelper instance).

https://github.com/zendframework/zend-expressive-zendviewrenderer/blob/master/src/ZendViewRendererFactory.php

In any case, I think this small change should suffice to relieve most of the confusion.

• Is this related to documentation?
  • Is it a typographical and/or grammatical fix?
  • Is it new documentation?

Thanks, @shadyan! I reviewed the actual requirements, and made a few other changes on update to reflect how the factory works. Thanks for prodding me via this patch!
