Feature: #107837 - Sitemap route enhancers provided via site set 

See forge#107837

Description 

The SEO extension now ships its sitemap route enhancers as part of the typo3/seo-sitemap site set. When this set is used as a dependency, the route enhancers for XML sitemaps are automatically configured.

This enables clean URLs for sitemaps out of the box:

  • /sitemap.xml - Main sitemap index
  • /sitemap-type/pages - Pages sitemap

Previously, these route enhancers had to be manually configured in each site's config.yaml.

Impact 

Sites using the typo3/seo-sitemap set no longer need to manually configure sitemap route enhancers. The clean URLs are available automatically.

Sites can still override or extend the route enhancers in their site configuration if needed.
