Is your feature request related to a problem? Please describe.
When running jf docker scan : --format=simplejson, we don't get the CWEs and CVSS vectors

Describe the solution you'd like to see
As behind the scene, we're calling the Xray api GET /api/v1/scan/graph/?include_vulnerabilities=true
and it does return these fields, we should include them in the final response

Describe alternatives you've considered
