{{#invoke:VersionHistoryItems|get|page=..}}
* if page is empty, current page is used
* this function return an array with parameters:
  * Current version description (text)
  * Current version number (text)
  * Current version date (text)
  * versionHistory (holds subarrays with values from "version History item" multiple instance templates)

Debug console tests:

without page parameter:
=p.get(mw.getCurrentFrame():newChild{title="test"}) 
with page parameter (use current page):
=p.get(mw.getCurrentFrame():newChild{title="test",args={["page"]="Persoon/1"}}) 
with empty page parameter (use current page):
=p.get(mw.getCurrentFrame():newChild{title="test",args={["page"]=""}})
