Bumps sylius/sylius to ~1.13.0 || ~1.14.0 and PHP to ^8.1. Drops 1.11 and 1.12.

Sylius API

No class in src/ needed a change:

• sylius.product_variant_resolver.default was not removed in 1.13, only the tag of that name was.
  The service id is unchanged in 1.13 and 1.14, so the injection in ItemFactory stays as is. The
  1.14-only alias sylius.resolver.product_variant.default is deliberately not used, because it does
  not exist in 1.13.
• The session.factory decoration and EventsBag extends FlashBag are unaffected by Symfony 6.4.
• In 1.14 ResourceControllerEvent is an alias of Sylius\Resource\Symfony\EventDispatcher\GenericEvent,
  which extends Symfony's GenericEvent, so the listener type hints still match.

Test application

It was still on the 1.11/1.12 skeleton and could not boot on 1.13:

• registered SyliusStateMachineAbstractionBundle, otherwise the container fails on the missing
  sylius_abstraction.state_machine service
• removed config/sylius/1.11 and 1.12 and the 1.11 shim bundle
• replaced Swiftmailer with Symfony Mailer
• removed the dead package.json.~1.11.0.dist and package.json.~1.12.0.dist

Tooling

• ecs.php crashed on ECSConfig::parameters(), rewritten for the current API
• phpstan.neon moved to excludePaths and error identifiers, still level max
• CI matrix: PHP 8.1-8.3, Symfony ^5.4/^6.4, Sylius ~1.13.0/~1.14.0

Verification

Checked against Sylius 1.13.17 and 1.14.20 on PHP 8.1:

• phpstan (max), psalm, phpspec, phpunit, behat, composer validate --strict and
  doctrine:schema:validate green on both
• all listeners present in debug:event-dispatcher, decorator present in debug:container session.factory
• events actually emitted: view_item_list, view_item, add_to_cart, view_cart, begin_checkout,
  search and add_address_info from a shop walkthrough, plus purchase, remove_from_cart,
  add_payment_info, login and sign_up dispatched through the booted kernel
• installed into a clean sylius/sylius-standard 1.14 and verified both the default template and a
  custom templateName

Known issues, not fixed here

• CheckoutEventFactory::addShippingInfo() throws on an order without shipments, because
  Collection::first() returns false and ?-> does not short-circuit on it. Pre-existing.
• The first request of a new anonymous visitor drops its event, since the template is guarded by
  app.session.started. Reproduces on 1.12 too, so not a regression.
