Allow moving a HistoricalWorkPage but disable creation

[SharmaineLim]

No ticket

Description of Changes Made

Currently, we cannot create nor move historical work pages.

While we still want to keep creation of these page types disabled, we want to be able to move them around to a different work index.

How to Test

Try to move a historical work page to a different work index page.
