Change Post Comments to Query Comments

[scruffian]

Description

Post Comments isn't shipping in 5.9 so trying Query Comments instead as proposed in #179

Screenshots

Testing Instructions

1. Open a post/page with comments and see what they look like

Does this need to have the post comments form in it too? I don't see the ability to add comments otherwise.

Also... how much styling is possible here? We'd like it to look like it does in trunk.

[scruffian]

I can't find a way to add the form without using the post comments block, which isn't shipping in 5.9. I'm not sure if this will be possible...

I'm able to place it in manually via the site editor, and that generally seems to work?

<!-- wp:comments-query-loop -->
<div class="wp-block-comments-query-loop"><!-- wp:comment-template -->
<!-- wp:post-comment-author {"isLink":true} /-->

<!-- wp:post-comment-date {"format":"F j, Y g:i a","isLink":true,"fontSize":"small"} /-->

<!-- wp:post-comment-content /-->
<!-- /wp:comment-template --></div>
<!-- /wp:comments-query-loop -->

<!-- wp:post-comments-form /-->

I'm confused about how this is expected to work in 5.9.

The post-comment-author, post-comment-date, post-comment-content, and post-comments-form are all currently marked as experimental.

[jffng]

Can we use blocks that are marked as experimental, they just don't show up in the inserter?

[kjellr]

No, that doesn't sound right.

Left a comment here to get some clarification: WordPress/gutenberg#35979 (comment)

[michalczaplinski]

Hi folks, I've noted here that I don't think we should use the Comments Query Loop block in the twentytwentytwo as it's still very basic and not ready to be included in 5.9.

[jffng]

I think we can close this since post-comments will now be used in 5.9: WordPress/gutenberg#36132

Thanks for pushing the conversation forward with the PR @scruffian.
