fix(ui): published, draft and changed labels should now be correctly displayed (#8382)

Fixes the issue where the published or changed document is always shown
as "Changed" instead of "Published" or "Draft"

Statuses:
- Published - when the current version is also the published version
- Changed - when the current version is a draft version but a published
version exists
- Draft - when the current version is a draft and no published versions
exist
