This PR updates the type declaration (docblock) of the DefaultContainer::$services to the more specific array<string, object> and removes the resolved phpstan-baseline error. This type is derived as follows: within the DefaultContainer::__construct(), the keys are represented by class-string and mapped to values of type object. Additionally, DefaultContainer::setInstance() uses string type for keys and parameter $service is documented as type object, meaning that only type object occurs as value in DefaultContainer::$services.
As a logical consequence, DefaultContainer::get() returns objects based on the aforementioned, and InjectorInterface::create() which is also said to return type object.
Although the DefaultContainer::get() is inherit from the ContainerInterface::class which has return type mixed, the child is allowed to have a more specific return type based on covariance.
