Describe the Bug.

The admin panel's "unpublish" feature does not work as expected, as described in the reprod steps.

Recommended solution: replace "unpublish" with "Revert to...." which allows you to select any previous published version to revert to, or "Unpublish" the entire doc.

Related issue: #11942

Reproduction Steps

1. On a collection with autosave and draft enabled, create a new document and publish.
2. You should have v1 - initial doc, v2 - autosave, v3 - current published version.
3. Make some changes - v4 is created with status "autosave, draft".
4. Publish v4, creating v5 with status "published".
5. Click "unpublish" on the newly created v5.
6. The document leaves v5 as "published" and creates a v6 with status "draft"....

So, your newly added changes are left intact, (not "unpublished"), and there is no way to fully "unpublish" a document/post unless you delete it or manually set status: draft on each version of the document.
