Item with a draft version shows a Version History table containing only the current version #6262

Describe the bug

Anonymous users can tell whether an item has a draft version in progress (due to presence of Version History table, see screenshot above), even though the REST contract explicitly says they should not be able to:

Due to the restriction applied to this flag anonymous users will be unable to discover that a new version is currently under review.

Observed on sandbox.dspace.org.

To Reproduce

Ensure the REST API has versioning enabled (true on sandbox.dspace.org).

1. Go to any Item that does not have any version. Observe that no Version History table is shown.
2. Log in as admin, create a new version of the Item (do not deposit it).
3. Open Item page in a new window (incognito mode). Note the Version History table is shown with a single record.

Expected behavior

Anonymous users should not be able to discover that a new version is under review.

The Version History table should be shown only if there are >= 2 published items (but that's only my opinion!)

As soon as the new version is created, still a draft, the custom URL rotation happens. The custom URL still redirects to this item, but hovering over URLs shows a UUID instead of a friendly URL slug
