fix(lambda-event-sources): update s3-event-source to accept IBucket (#…

…28943)

### Issue # (if applicable)

Closes #4323 

### Reason for this change

S3EventSource should accept `IBucket` instead of `Bucket`.
`aws_s3.Bucket.from_bucket_name(...)` or `aws_s3.Bucket.from_bucket_arn(...)`, etc. returns aws_s3.IBucket type

### Description of changes

Based on @otaviomacedo 's comment in #25782 , a new class `S3EventSourceV2` is implementd to accept `IBucket` instead of `Bucket`. And avoids breaking changes.
