Describe the bug

With keyName property being deprecated (#28138), creating aws_ec2.KeyPair and passing it to aws_ec2.Instance does nothing.

Expected Behavior

Make sure the keypair is associated with the instance when passed through keyPair property.

Current Behavior

keypair does not get associated with the instance.

Reproduction Steps

const keyPair = new ec2.KeyPair(this, 'KeyPair', {});
 this.instance = new ec2.Instance(this, 'EC2Instance', {
      vpc: props.vpc,
      vpcSubnets: { subnetType: ec2.SubnetType.PUBLIC },
      securityGroup,
      instanceType: ec2.InstanceType.of(ec2.InstanceClass.T3, ec2.InstanceSize.MICRO),
      machineImage: ec2.MachineImage.latestAmazonLinux2023(),
      keyPair,
      userDataCausesReplacement: true,
      ssmSessionPermissions: true,
    });
