Provisioning - Template extraction always sets page as Published

[Magnus-K-work]

Found in: 1.21.0

How to reproduce:

1. Set up a SharePoint site, and add a Page as draft only
2. Run PnP.Framework provisioning to extract a template from that page (or site)
3. Apply the template to another SharePoint site
4. Examine the version history of new page => It is already published

Why this is an issue:
If copying a site with news, it is likely that the news needs to be updated for the new site. So, if any news pages already has a published version, that version will instantly be visible to visitors to the site.

Problem found:
In pnpframework\src\lib\PnP.Framework\Provisioning\ObjectHandlers\Utilities\ClientSidePageContentsHelper.cs, at line 109 the Published property of the extractedPage object is set to true. This will control if page will be created as a Published page later when applying the template to a SharePoint site.
