(aws_opensearchservice): i4g instances say they need EBS #31764
Description
Describe the bug
Attempting to build an opensearch.Domain object with an opensearch.CapacityConfig object which specifies ig4.2xlarge as its data_node_instance_type parameter yields an error with cdk synth, indicating that ig4.2xlarge instance types require EBS storage.

Expected Behavior
I expect to be able to create an Opensearch cluster using i4g instances without using EBS.
Current Behavior
An error is thrown:

)Possible Solution
The list of instance types that does not use EBS appears to be outdated. i4i and i4g both don't use EBS according to https://docs.aws.amazon.com/opensearch-service/latest/developerguide/supported-instance-types.html
