 The return type for `wp_get_raw_referer` indicates it returns
 `string|false`. However, this is not the case if the user provided
 `$_REQUEST['_wp_http_referer']` variable is an array for example.

 This results in PHP 8.x fatals in code that assumes this function only
 returns strings/booleans.

 {{{
 strpos( wp_get_raw_referer(), 'foo' );
 }}}
