Subject: [PATCH] Code Modernization: Update parameter names in the
 `WP_Block_List` class.

This makes the parameter names consistent with the `ArrayAccess` interface.

Reference: [https://www.php.net/manual/en/class.arrayaccess.php PHP Manual: The ArrayAccess interface].

Follow-up to [48159].

Props rahmohn.
See #58976.
