Low severity badge is blackish instead of yellow in the finding modal

Summary

The low severity badge is dark instead of yellow in the following places:

1. finding modal
2. vulnerability count card
3. group security dashboard
4. vulnerability row

Steps to reproduce

1. Go to gitlab-examples/security/security-reports!52 (closed)
2. Click on a finding that is low severity

Analysis

The color orange-200 is not being applied due to a refactor. This refactor, among other things, replaced text-warning-200 by gl-text-orange-200 but this last css class does not exist.

However, when further researching this issue, it was found that there is an inconsistency in orange colors used for low severity security items. In fact, all low severity items should be orange-300 and not orange-200 as defined in Pajamas. See comment for more context.

Implementation steps

• replace occurrences of gl-text-orange-200 to gl-text-orange-300

Verification steps
