Wrong robots meta output

[joostdevalk]

in default-filters.php, we add a new action:

`if ( isset( $_GETreplytocom? ) )

add_action( 'wp_head', 'wp_no_robots' );`

the issue is, wp_no_robots outputs noindex, nofollow. The noindex is fine, the nofollow stops any link equity from that URL, so that's actually a bad idea. Just noindex alone would be fine. Setting to priority high and severity to major as this is basically a regression.
