Issue # (if applicable)
Closes #36698
Reason for this change
OI2 is an OpenSearch-specific instance type that uses local NVMe storage and does not support EBS volumes. Currently, CDK validation incorrectly rejects OI2 instance types when ebs: { enabled: false } is specified, throwing:
ValidationError: EBS volumes are required when using instance types other than R3, I3, R6GD, I4G, I4I, I8G, IM4GN, R7GD or R8GD.
