docs(cloudfront): update Distribution example to use S3BucketOrigin instead of deprecated S3Origin (#34525)

### Issue # (if applicable)

Closes #34469.

### Reason for this change

The [Distribution](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_cloudfront.Distribution.html#example) documentation still uses the deprecate [origins.S3Origin](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_cloudfront_origins.S3Origin.html) api.

### Description of changes

Use [S3BucketOrigin.withOriginAccessControl(bucket, props?)](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_cloudfront_origins.S3BucketOrigin.html#static-withwbroriginwbraccesswbrcontrolbucket-props) instead of [origins.S3Origin](https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_cloudfront_origins.S3Origin.html).



### Describe any new or updated permissions being added
