Drupal 11.4 compatibility: RedirectPathProcessorManager calls removed PathProcessorManager::addInbound() (fatal)

Problem/Motivation

On Drupal 11.4.0, any request fatals with:

Error: Call to undefined method Drupal\Core\PathProcessor\PathProcessorManager::addInbound() in Drupal\redirect\PathProcessor\RedirectPathProcessorManager->addInbound() (line 39 of modules/contrib/redirect/src/PathProcessor/RedirectPathProcessorManager.php).

Drupal 11.4 rewrote Drupal\Core\PathProcessor\PathProcessorManager to use constructor-injected autowired iterators (#[AutowireIterator(tag: 'path_processor_inbound')] / path_processor_outbound) and REMOVED the addInbound() / addOutbound() service-collector methods (and getInbound()). RedirectPathProcessorManager extends that manager, overrides addInbound() calling parent::addInbound() (now undefined) and iterates via getInbound() in processRedirectInbound() — both gone — so it fatals. The module's redirect.services.yml also still registers via { name: service_collector, tag: path_processor_inbound, call: addInbound }.

Steps to reproduce

1. Install Drupal 11.4.0 with the Redirect module (8.x-1.x) enabled.
2. Load any page. The site returns HTTP 500 with the fatal above.

Proposed resolution

Follow core 11.4's pattern in RedirectPathProcessorManager: inject the inbound/outbound processors via constructor #[AutowireIterator(tag: 'path_processor_inbound')] / path_processor_outbound and call parent::__construct(); remove the addInbound() override and the registration-time applies() gating; in processRedirectInbound() iterate $this->inboundProcessors, skipping PathProcessorFiles (and AliasPathProcessor when $skip_alias). Update redirect.services.yml to autowire: true with $config_factory: '@config.factory' and drop the service_collector tag. Needs to stay compatible with Drupal 10.4/10.5 as well (the removed methods still exist there), so the change should be guarded or the module's minimum core raised accordingly. See the issue fork and merge request !199 linked on this issue.

API changes

• Drupal core 11.4 removed PathProcessorManager::addInbound()/addOutbound()/getInbound(); this fix aligns RedirectPathProcessorManager with the new autowired-iterator pattern instead of the removed service-collector methods (module-internal, not a Redirect module public API change).
