Are there any plans to also update the OpenSearch VectorCollection CDK construct to use "Private" as the access type (similar to the options provided in the AWS Console)? As of now when we use the CDK to create an OpenSearch VectorCollection it defaults to using the access type "Public". The new VPC helper methods created as a result of this ticket would also to create create VPC endpoints, but the underlying OpenSearch serverless collection would still be configured as "Public".
