Validate the requested sitemap is a string before attempting to use it in a provider. This prevents `WP_Sitemaps_Registry::get_provider()` from triggering a fatal error in more recent versions of PHP. The errors can be triggered by items outside the site owner or developers control (such as a user visiting `?sitemap[foo]=bar`) so the code fails silently to avoid filling error logs with unfixable errors. Props costdev, dd32. Fixes #56336. Built from https://develop.svn.wordpress.org/trunk@53838 git-svn-id: http://core.svn.wordpress.org/trunk@53397 1a063a9b-81f0-0310-95a4-ce76da25c4cd
