New DS analyzer always generates a Dependency Scanning Report

What does this MR do and why?

This modifies the latest CI template for Dependency Scanning to export the DS security report generated by the new DS analyzer as a CI job report artifact.

This will reintroduced the behavior that exists in the legacy Gemnasium analyzer by bringing back security scan results in the running CI pipeline. The new analyzer is now generating that report by default on GitLab 18.5 and above thanks to gitlab-org/security-products/analyzers/dependency-scanning!349 (merged)
