AWS CDK CLI: China partition not taken into account when validating notification Sns Topic

### Describe the bug

The `cdk deploy` commands allows you to specify SNS topics for CloudFormation notifications with the `--notification-arns` option.

However, when deploying in a China region, with a valid SNS Topic in China, the command will error out with:

```
Notification arn arn:aws-cn:sns:cn-northwest-1:012345678901:topic is not a valid arn for an SNS topic
```

### Expected Behavior

The CLI should allow the China partition (aws-cn) when validating the SNS topic.

### Current Behavior

The CLI exits.

### Reproduction Steps

```
cdk deploy --notification-arns arn:aws-cn:sns:cn-northwest-1:012345678901:my-topic
```

Reproduce the failure with cdk deploy --notification-arns using the supplied arn:aws-cn SNS ARN, then trace the CLI's notification ARN validation. The issue is done when a valid China-region SNS topic is accepted while invalid SNS ARNs are still rejected.
