* fix: a bug of diff logic when multiple oval-defs hav certain CVE-ID and same updated_at
Commented out beause a bug of diff logic when multiple oval defs has certain CVE-ID and same updated_at.
If these OVAL defs have different affected packages, this logic detects not-updated-CVE-ID as updated.
This logic will be uncommented after integration with ghost https://github.com/knqyf263/gost
