PROVCON-4978 - Nested pages not being publishing for MCP content via API

Goal

The goal of this PR is to address following errors caused by publish-portal-content.sh script

Cannot construct instance of `com.smartbear.swaggerhub.portal.apimodel.generated.model.Source`, problem: Unexpected value ''

Bad Request: Documents can be modified only via Documents API

Design

Does not apply

Changeset

• Added extra condition to check if source is not null, nor empty string in portal_product_document_markdown_patch and portal_product_toc_markdown_post
• Added extra condition to check if document_id is not null, nor empty string in portal_product_document_markdown_patch
• Removed type parameter from portal_product_toc_markdown_patch as it is no longer supported by Portal API

Testing

Tested by running Publish Portal Content workflow, that calls affected script under the hood:
