Amplify Gen2 cli documentation refers to Backend construct that doesn't exist in aws-cdk-lib

[juranki]

Describe the content issue:

Section Generate codegen for CDK app using a joint "AmplifyBackendStack" construct in CLI commands -reference has following snippet:

import { Construct } from 'constructs';
import { App, Backend } from 'aws-cdk-lib/aws-amplify';

export class MyAmplifyStack extends cdk.Stack {
  constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    new Backend(this, "Backend", { /* ... */ });
  }
}

But Backend construct doesn't exist in aws-cdk-lib/aws-amplify or @aws-cdk/aws-amplify-alpha.
