Feature: #94206 - Add excludePagesRecursive option to XML sitemap generation

See Issue #94206

Description

With this option you can exclude pages recursively in the XML sitemap:

plugin.tx_seo {
    config {
        xmlSitemap {
            sitemaps {
                pages {
                    config {
                        # comma-separated list of page UIDs which should be excluded recursively
                        excludePagesRecursive = 2,3
                    }
                }
            }
        }
    }
}

Impact

The new option enables integrators to easily exclude pages recursively in the XML sitemap
