Non OS packages are present in the CycloneDX SBOM report generated by Trivy (Container Scanning)

Summary

The Container Scanning job using the Trivy scanner is generating an SBOM cycloneDX artifact report that contains OS packages but apparently also Language packages like pypi ones, even if the "Report language-specific findings" option is not enabled (disabled by default).

See this cylcloneDX.json example

What is the current bug behavior?

Non OS packages like pypi purl type are reported in the CycloneDX report generated by trivy even if the "Report language-specific findings" option is not enabled.

What is the expected correct behavior?

Non OS packages like pypi purl type are only reported in the CycloneDX report generated by trivy when the "Report language-specific findings" option is enabled.
