Frontend: Add a badge representing the feature version in the CI/CD Catalog
## Overview
We could add a badge that represents that the CI/CD Catalog is in the experimental phase. Once we release the **Beta**, we could update the badge to the Beta label.

### Proposal
Add a feature version badge next to the `CI/CD Catalog` UI text on the index page.

- `8px` gap between the text and the badge.
