Subject: [PATCH] Display both subject and talk subpages for Special:MovePage

Editors were only able to see current page subpages, not subpages of
the corresponding talk page (if there is one). Consolidate display
routine in showSubpagesList. Conditionally show as needed

Adds 'movesubpagetalktext' to en.json for description of second
bulleted list.

Bug: T140026
Change-Id: Id5bb52411ab8249eda180b13aef7d8884064b5db
