Description
Previously, malcontent would remove nested archives which failed to extract which could potentially leave malicious content. A better approach is to preserve these archives so that malcontent can attempt a best-effort scan of the archive bytes.
Fix: https://github.com/chainguard-dev/malcontent/pull/1383
