Listing Harbor CLI on ArtifactHub

[Vad1mo]

ArtifactHub is a popular place to discover helm charts but also container images. CNCF has its presence on ArtifactHub

I was able to add the image for ArtifactHub to crawl. However there is a problem as the image does not have the right metadata.

We encountered some errors while tracking repository harbor-cli.

Some or all of these errors may be just warnings, and it's possible that your packages have been still indexed properly. However, it'd be great if you can take a look at them just in case there is something missing or failing in your repository that may affect how your content is displayed on Artifact Hub.

error preparing package (tag: latest): 3 errors occurred:

* required metadata field not provided: org.opencontainers.image.created

* required metadata field not provided: org.opencontainers.image.description

* required metadata field not provided: io.artifacthub.package.readme-url

Task would be to extend the Dagger workflow and add the minimum required and recommended metadata
