Link DAST spec fixtures to ensure they stay in sync
The following files should be linked so that they stay in sync for their respective DAST-related tests.
- https://gitlab.com/gitlab-org/security-products/dast/blob/master/test/expect/site-basic.json
- https://gitlab.com/gitlab-org/gitlab-ee/blob/master/spec/fixtures/security-reports/master/gl-dast-report.json
- https://gitlab.com/gitlab-org/gitlab-ce/blob/master/spec/fixtures/security-reports/master/gl-dast-report.json
Changes may be required in all three of these projects to accomplish this.
