Calcaulate and include CVSS Vector and score

GitLab has introduces CVSS Vectors:
- https://gitlab.com/gitlab-org/security-products/security-report-schemas/-/commit/03a58b32e9d2c43d45934fbe750ef4580aa7a3f6

We can add it to system output to provide more information about vulnerability

We can also calculate score using: https://pypi.org/project/cvss/

add it to test case name like (Severit: Critical) (Score: 9.8) and sort test cases.
