bug(aws-kinesisfirehose-s3): fixed name resource causes name collision

[biffgaut]

A fixed resource name causes a resource name collision when deploying 2 aws-kinesisfirehose-s3 constructs in the same stack.

Reproduction Steps

import * as cdk from 'aws-cdk-lib';
import { Construct } from 'constructs';
import { KinesisFirehoseToS3 } from '@aws-solutions-constructs/aws-kinesisfirehose-s3';

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

new KinesisFirehoseToS3(this, 'test-firehose-s3', {});
new KinesisFirehoseToS3(this, 'second-instance', {});

}
}

Error Log

(...)/node_modules/constructs/src/construct.ts:423
throw new Error(There is already a Construct with name '${childName}' in ${typeName}${name.length > 0 ? ' [' + name + ']' : ''});
