Subject: refactor(components): split Comment component into 3 components

* add ApprovedComment, PendingComment and ReplyCommentForm components
* let consumer handle reply form visibility
* move structured data into article page (each article already has the
comments data and already handle json ltd schema so I prefered to move
the schema in the final consumer instead of adding a script element
foreach comment)
