(aws-ec2): Cannot deploy SecurityGroup with allowAllIpv6Outbound: true

[Tietew]

Describe the bug

Per #22279 (CDK 2.45.0), allowAllIpv6Outbound is added to SecurityGroup.
But deployment is failed when allowAllIpv6Outbound: true

Expected Behavior

The stack is successfully deployed.

Current Behavior

Deployment failed.

❌ CdkIpv6Stack failed: Error: The stack named CdkIpv6Stack failed creation, it may need to be manually deleted from the AWS console: ROLLBACK_COMPLETE: CIDR block ::/0 is malformed (Service: AmazonEC2; Status Code: 400; Error Code: InvalidParameterValue; Request ID: xxx; Proxy: null)

Reproduction Steps

Deploy following stack:

import * as cdk from 'aws-cdk-lib';
import { Construct } from 'constructs';
import * as ec2 from 'aws-cdk-lib/aws-ec2';

class CdkIpv6Stack extends cdk.Stack {
  constructor(scope: Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);
    const vpc = ec2.Vpc.fromLookup(this, 'Vpc', { isDefault: true });
    new ec2.SecurityGroup(this, 'SecurityGroup', { vpc, allowAllIpv6Outbound: true });
  }
}

const app = new cdk.App();
new CdkIpv6Stack(app, 'CdkIpv6Stack', {
  env: { account: 'xxx', region: 'ap-northeast-1' },
});

Possible Solution

Created template contains "CidrIp": "::/0", but is should be "CidrIpv6": "::/0".
