      creates a vulnerability from finding and attaches it to the vulnerability
      when finding id is unknown
        responds with expected error
      when a vulnerability already exists for a specific finding
        rejects creation of a new vulnerability from this finding
      behaves like forbids access to vulnerability API endpoint in case of disabled features
        when security dashboard feature is not available
          responds with 403 Forbidden

The first error is expected this action to be allowed for admin role. Expected status code: any of 200, 201, 204, 302, 304 Got: 500 but then the second error is due to rspec-retry which doesn't unset :@__#{USER_ACCESSOR_METHOD_NAME}_patched instance variable: https://gitlab.com/gitlab-org/gitlab/-/blob/6e7e449dba65077aca8faabc63848ebdcf662444/spec/support/helpers/access_matchers_helpers.rb#L64-66
