[6.8 HelpHub] Post Author block deprecation

[carolinan]

Issue Description

There is a plan to deprecate the Post author block in WordPress 6.7.
The existing blocks that are already placed will continue to work, but users will not be able to add the block again from the inserter.

See this issue for the details WordPress/gutenberg#55352
Please re-check this issue closer to the release of 6.7 to confirm that the plan was followed through.

Why is this a problem?

When the block is deprecated, the page will be outdated.

Suggested Fix

I found the following example of a page for a deprecated block:
https://wordpress.org/documentation/article/button-block/

And this list should be updated:

Heads up @WordPress/docs-issues-coordinators, we have a new issue open. Time to use 'em labels.
