Editor/Docs: The place where `post_submitbox_minor_actions` is fired is misleading in the related DocBlock

[audrasjb]

The place where post_submitbox_minor_actions is fired is misleading in the related DocBlock.

It says "Fires before the post time/date setting in the Publish meta box" but it fires right at the end of the .minor-publishing-actions <div> element.

I think we should rather indicate that it fires "after the save and preview settings in the Publish meta box" or "before the post status setting in the Publish meta box". Both are accurate, but I think the first one is better as the action hook is placed inside the <div> that contains both the save and preview settings.

Please also props @bedas for their feedback on DevHub user contributed notes.

First proposal: Fires after the Save and Preview settings

[audrasjb]

Another proposal: Fires before the post status setting

[audrasjb]

Added two patches to handle both possibilities, but I'd say the first one is the more accurate (see ticket description).

In 51732:

Docs: Correct the post_submitbox_minor_actions hook description.

The action fires after the Save Draft (or Save as Pending) and Preview (or Preview Changes) buttons in the Publish meta box.

The previous description stated that the action fires before the post date/time setting, which was not quite correct, as there are also post status and visibility settings between the action and the date/time setting.

Props bedas, audrasjb.
Fixes #54045.
