RustFS: Anonymous ListObjectVersions bypasses RestrictPublicBuckets through the ListBucket fallback

RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.12, an anonymous ListObjectVersions request in rustfs/src/storage/access.rs that lacks a direct bucket-policy grant falls back to an s3:ListBucket check and returns before the policy_allowed path applies deny_anonymous_table_data_plane_if_needed and RestrictPublicBuckets, so a bucket that permits anonymous listing can continue exposing version listings after an operator enables the public-access control. The bypass affects GET /<bucket>?versions= and can disclose object version metadata even though equivalent GetObject requests are denied. This issue is fixed in version 1.0.0-beta.12.
