The conditional tag article:published_time outputs for posts but not for pages

Issue moved from Jira: https://yoast.atlassian.net/browse/IM-774
Reporter: @michaelbriantina

• I've read and understood the contribution guidelines.
• I've searched for any related issues and avoided creating a duplicate issue.

Please give us a description of what happened

Description
In our documentation here, we state that we output the article:published_time for both posts and pages.

When creating a new post, it outputs both the article:published_time and article:modified_time.

However, when creating a new page, it doesn't output the article:published_time. It does output the article:modified_time though. Also, the datePublished and dateModified schema are also outputting accordingly.

Is this a bug or do we just need to update our developer documentation for the article:published_time section?

Impact
This could potentially cause issues for any websites or crawlers that use the article:published_time conditional tag.
"The article:published_time doesn't output for pages which isn't in line with our documentation"

WP: 6.5.4

Some feedback that we also output article:modified_time (but not article:publish_time on custom post types).

To be clear, the documentation describes the correct behaviour.

On post and page post types, we should output both of these tags. On other post types, we should not output either tag (because we can’t reliably assume that these are appropriate for the content type).

@ Jannes Do we need to re-open this following our discussions?

The published date is only shown on posts. The wpseo_opengraph_show_publish_date can be used to add additional posttypes to add the publish date to other posttypes.

I have proposed this change to the docs: https://github.com/Yoast/developer-docs/pull/107. Since there is a filter present, I assume this behavior is intentional, so I’m closing this report.

It would also be nice to have author info as many pages are published on dates that are prior to competitors with better authors. Also the opengraph twitter and other stuff should be available at least for graphql
