feat: add fields for `json` and `SBOM` formats with info that Trivy doesn't support OS

[DmitriyLewen]

Description

Trivy has unsupported OSes (e.g. Fedora). To avoid cases where the user doesn't see a log about this (e.g. when the -q flag is enabled) and to make machine processing easier, we need to add fields for this information:

• json format (in OS struct)
• SBOM formats (in properties)
