Peter Wilson 6219eb95bf Sitemaps: Prevent invalid provider names throwing errors. ...

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.
