Describe the bug

I want to use an externally created bucket as an event notification source for a lambda

Expected Behavior

An IBucket can be used as the notification source

Current Behavior

Type errors. An IBucket cannot be assigned to a Bucket.

Reproduction Steps

import * as core from "aws-cdk-lib";
import * as event_sources from "aws-cdk-lib/aws-lambda-event-sources";
import * as s3 from "aws-cdk-lib/aws-s3";

const app = new core.App()
const ibucket = s3.Bucket.fromBucketName(app, "IBucket", "IBucket");
const eventSource = new event_sources.S3EventSource(ibucket, {events: [s3.EventType.OBJECT_CREATED]})

TS2345: Argument of type 'IBucket' is not assignable to parameter of type 'Bucket'.

Possible Solution

Since addEventNotification is the only method used by S3EventSource and is available on an IBucket, I think it should be safe to loosen the type restriction to IBucket.

Coercing the type and deploying works.
