S3 explicitly documents this action as owner-only ("To retrieve the versioning state of a bucket, you must be the bucket owner." — https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetBucketVersioning.html), and the handler enforced that with an extra auth.IsAdminOrOwner check on top of VerifyAccess. Real S3 behaves differently: verified against AWS that a bucket policy explicitly denying s3:GetBucketVersioning denies the bucket owner itself, and that an Allow grants the action to a principal that doesn't own the bucket. It goes through ordinary bucket policy/ACL evaluation like any other bucket subresource read, which is what the write side, PutBucketVersioning, already did here. Removes the extra check along with auth.IsAdminOrOwner, which had no other call site.
