Plugin Directory: Indicate developer review replies on plugin pages

[hlashbrooke]

In the new plugin directory design, we show the latest 2 reviews on the plugin page with a link to go and view the rest of them. What we don't show, however, is the number of comments a review has or whether the plugin developer has responded. I find that it's really useful to know if the plugin developer has responded when I see a 1 or 2 star review as the reviewer is often misguided and the developer has then pointed them in the right direction. It's nice to be able to see this info up front without clicking through to the actual review.

To remedy this, we could one of two things:

1. Show the number of comments next to the review.
2. Show a badge or link to indicate that the plugin developer has responded.

I'll attach a couple of screenshots here showing what I mean - the content in the screenshots was done quickly in the Inspector, so it's very basic and could definitely be done in a more visually appealing way I'm sure.

Moving this to the support forums as the reviews are in the forums.

Reviews are in the forums, but this ticket is about the wporg-plugins-reviews shortcode​ in the plugin directory :)

Adds a comment count next to the review.

This is is the outcome of 1805.comment.count.diff. The 2nd example where the comment is piped beside the posting date is not implemented.

[dufresnesteven]

Thanks @dd32. Using _bbp_reply_count to get the count instead.

Any concerns implementing it?
