Add support to the "AWS::ServiceCatalog::AcceptedPortfolioShare" resource for the "PortfolioShareType" property

### Name of the resource

AWS::ServiceCatalog::AcceptedPortfolioShare

### Description

Currently, it is not possible to accept Service Catalog portfolios shared on the Organizational level with CloudFormation. The "AWS::ServiceCatalog::AcceptedPortfolioShare"[1] resource type does not include any property to specify the method of sharing. Attempts to accept a portfolios shared at the Organizational level using this resource result in the following error: "Portfolio port-xxxxxxxxx not found."

In comparison, the "AcceptPortfolioShare" API allows users to accept portfolios that are shared at the Organizational level using the "PortfolioShareType" parameter[2].

Start by comparing the AWS::ServiceCatalog::AcceptedPortfolioShare resource documentation with the AcceptPortfolioShare API reference, focusing on PortfolioShareType and organizational sharing. Done means CloudFormation can accept organizationally shared portfolios through this resource without the portfolio-not-found error.
