Hi 👋

The ociReference here refers to the collection metadata artifact instead of the individual
templates. Hence, the author needs to only add a single entry irrespective of the number of Templates that might exist in their repository.

Can you help update this? thanks!

[samruddhikhandale]

Can you help change the visibility of this "metadata" package (and your Template package) to public? The index won't be able to crawl the Templates in demos-by-igwejk/devcontainer-templates if it's private.
