Feature: #106363 - PSR-14 event for modifying URLs for redirects:integritycheck

Description

A new PSR-14 event \AfterPageUrlsForSiteForRedirectIntegrityHaveBeenCollectedEvent is added which allows TYPO3 Extensions to register event listeners to modify the list of URLs that are being processed by the CLI command redirects:checkintegrity.

Example

The event listener class, using the PHP attribute #[AsEventListener] for registration, adds the URLs found in a sites XML sitemap to the list of URLs.

use TYPO3\CMS\Redirects\Event\AfterPageUrlsForSiteForRedirectIntegrityHaveBeenCollectedEvent;

final class MyEventListener
{
    public function __construct(
        private RequestFactory $requestFactory,
    ) {}

    #[AsEventListener]
    public function __invoke(AfterPageUrlsForSiteForRedirectIntegrityHaveBeenCollectedEvent $event): void
    {
        $pageUrls = $event->getPageUrls();

        $additionalOptions = [
            'headers' => ['Cache-Control' => 'no-cache'],
            'allow_redirects' => false,
        ];

        $site = $event->getSite();
        foreach ($site->getLanguages() as $siteLanguage) {
            $sitemapIndexUrl = rtrim((string)$siteLanguage->getBase(), '/') . '/sitemap.xml';
            $response = $this->requestFactory->request(
                $sitemapIndexUrl,
                'GET',
                $additionalOptions,

            $sitemapIndex = simplexml_load_string($response->getBody()->getContents());

                $sitemap = simplexml_load_string($response->getBody()->getContents());
                foreach ($sitemap as $url) {

            }

        $event->setPageUrls($pageUrls);
