Add support for Radius Recipe repositories

[willtsai]

Is your feature request related to a problem? Please describe.
Radius is a cloud native application platform. It enables developers and IT operators to collaborate on delivering and managing cloud-native applications. One of the key features is Recipes, which allow infrastructure to be preconfigured and packaged that enables a separation of concerns between IT operators and developers by automating infrastructure deployment. Users may leverage community contributed repositories and registries that house Recipes for them to use off the shelf, e.g. radius-project/recipes. We would like Artifact Hub to support listing of Radius Recipes to help users discover deployment Recipes that they may use.

Describe the solution you'd like
Recipes can be written in Terraform (pushed to git repos) or Bicep (published to OCI registries), so we would like to be able to list these in Artifact Hub.

Describe alternatives you've considered
So far we've only listed available recipes in the Radius community recipes repo, but it would be great to list other recipe repositories in one place. We've considered adding these listings to our documentation, but that is not self-service and thus unsustainable going forward.

Hi @willtsai 👋

Radius recipes would be a nice addition to Artifact Hub 🙂

We'll look into it and get back to you!
