Description

According to https://aws.amazon.com/about-aws/whats-new/2023/11/amazon-s3-enabling-object-lock-buckets/ , you can now enable Object Lock on an existing bucket.

However, the CloudFormation change set indicates that it requires replacement:

      "resourceType": "AWS::S3::Bucket",
      "replacement": "True",
      "scope": [
