Add internal stub for psr container, updating export-ignores

Description

Adding the stub doesn't have much impact here because most of the get's use aliases. It'll probably be more useful when psalm.xml goes to level 1 perhaps?

Would you accept a PR to update calls to $container->get('FormElementManager') to $container->get(FormElementManager::class) (And similar) ???

Yes please, we can also switch the official ones to be the class names, so from:

'aliases'            => [
    Annotation\AnnotationBuilder::class => 'FormAnnotationBuilder',
    Annotation\AttributeBuilder::class  => 'FormAttributeBuilder',
    FormElementManager::class           => 'FormElementManager',
],
'factories'          => [
    'FormAnnotationBuilder' => Annotation\BuilderAbstractFactory::class,
    'FormAttributeBuilder'  => Annotation\BuilderAbstractFactory::class,
    'FormElementManager'    => FormElementManagerFactory::class,
],

to

'aliases'            => [
    'FormAnnotationBuilder' => Annotation\AnnotationBuilder::class,
    'FormAttributeBuilder'  => Annotation\AttributeBuilder::class,
    'FormElementManager'    => FormElementManager::class,
],
'factories'          => [
    Annotation\AnnotationBuilder::class => Annotation\BuilderAbstractFactory::class,
    Annotation\AttributeBuilder::class  => Annotation\BuilderAbstractFactory::class,
    FormElementManager::class           => FormElementManagerFactory::class,
],

🚢 here meanwhile.

Thanks @gsteel!
