Expected or Desired Behavior

Built in fields, field refs and content types are included in the provisioning template when running Get-PnPProvisioningTemplate on a communication site.

Observed Behavior

When exporting fields with the Get-PnPProvisioningTemplate command, the following built in fields are included in the resulting XML.

Site fields:
_OriginalSourceSiteId, _OriginalSourceUrl, _OriginalSourceItemId, _OriginalSourceListId, _OriginalSourceWebId, _AuthorByline

Fielf refs on custom lists:
_ComplianceFlags, _ComplianceTag, _ComplianceTagWrittenTime, _ComplianceTagUserId, _IsRecord, ComplianceAssetId

Content Type: Repost Page

Are these fields, field refs and the content type really expected to be included in the provisioning template? Should these be kept or removed in the XML template before applying the template to a new site?

Steps to Reproduce

Run Get-PnPProvisioningTemplate -Handlers Fields,ContentTypes,Lists

Maybe a Special handling for the "Repost Page" content type is necessary.
