Add ArtifactHub packages to website

[thisisobate]

As part of our ongoing efforts in encouraging better developer experience across different CNCF projects, we figured it would be nice for projects to showcase their packages hosted on ArtifactHub by embedding directly on the website.

To embed all the necessary project-related packages, kindly follow this guide. You can as well view some examples:

• Keptn integration
• Keda
