Green DevOps: Why carbon measurement belongs in your CI/CD pipeline

What this post added

Introduced integrations with Eco CI and Carmen to measure and report on carbon emissions within GitLab CI/CD pipelines. Eco CI provides per-job emission data, while Carmen offers infrastructure-level insights into operational and embodied carbon. Provided examples of how to integrate these tools into `.gitlab-ci.yml` and discussed practical use cases for identifying and reducing carbon waste in pipelines and infrastructure.
