QA(fix): Move laminas/service-manager back to dev dependencies

Pretty unsure why it was moved from dev dependencies in laminas#129, but it seems to be wrong.

Still suggest section states:

> "laminas/laminas-servicemanager": "Laminas\\ServiceManager component to allow using the ValidatorPluginManager and validator chains",

so it is optional dependency and we should not be forced to install it, when we do not need it.
