Subject: [PATCH] Script Loader: Replace `str_contains()` usage in
 `wp-includes/script-loader.php`.

This avoids fatal errors on PHP < 8.0 if the file is included via `wp-admin/load-scripts.php` or `wp-admin/load-styles.php`, in which case the polyfills from `wp-includes/compat.php` are not loaded.

Follow-up to [55703], [55710], [55988].

Props ryelle.
See #58206.
