badges: add ArtifactHub; normalize CIIBestPractices

[philpennock]

We have an existing Artifacts Hub repository, based on the nats-io/k8s repo.

Including a badge which links to that repository should resolve the "Artifact Hub badge" item in the CLOMonitor report on nats.

While there, normalise the "CII Best Practices" badge to use markdown reference links, the same as all the other badges.

BTW https://artifacthub.io/packages/helm/nats/nats says the chart is not official.

Considering there are others charts like Bitnami-managed ones (https://artifacthub.io/packages/helm/bitnami/nats), would be nice to claim the official status here: https://artifacthub.io/docs/topics/repositories/#official-status.

Thanks @arm4b looks like we can open an issue in artifacts hub so that it is labeled as official.

I think a flow document I looked at had the link from the README to the helm chart in artifacthub as a pre-requisite for being able to verify the helm chart as official, but I don't have my notes from that available right now, to confirm.

Could be needed for the verified publisher ArctifactHub badge https://artifacthub.io/docs/topics/repositories/#verified-publisher? Which is already ✅ in place.
Having that as pre-req, it's now possible to get the official ArtifactHub badge per their guide.

And indeed, looks like it should be done via opening an Issue with a request.
