Get-PnPSiteTemplate - additional Handler needed for Page Templates only

[AndreSchiemann]

The use case is to export all published custom page templates from a (usally communication) website.

Currently you need to export all pages from the library "Site Pages"
$basetemplate = Get-PnPSiteTemplate -OutputInstance -IncludeAllClientSidePages -Handlers PageContents,Pages -Schema LATEST -PersistBrandingFiles
and afterwards iterate trough the collection of all exported pages:

{
    if($page.PromoteAsTemplate -eq $true)
    {
        #save this page template into a new $template object       
    }      
}

Thanks,
André
