Documented filter type wrong

[kkmuffme]

When running some static analysis tests we encountered a type documentation issue in:
https://github.com/Yoast/wordpress-seo/blob/trunk/inc/options/class-wpseo-option-wpseo.php#L217
https://github.com/Yoast/wordpress-seo/blob/trunk/admin/tracking/class-tracking.php#L223

should be @param string|false instead of @param string
