What this post added

This post announces the General Availability of the CI/CD Catalog, detailing its core features: components (template-type and upcoming CI Steps) and inputs interpolation. It explains how to access and use components, distinguishing between public and private components, and outlining differences between GitLab.com and self-managed deployments. Future plans include CI Steps becoming first-class catalog objects, enhanced security for catalog workflows, and analytics for component usage.
