🐛 Continue scanning when connect to one asset fails

[czunker]

Fixes #2080

[czunker]

With cnspec, this now looks like this:

cnspec scan k8s --discover container-images --config ~/workspace/mondoo/sa-edge-default.json                                                                                                                                                          
→ loaded configuration from /home/christian/workspace/mondoo/sa-edge-default.json using source --config
→ using service account credentials
→ discover related assets for 1 asset(s)

shall we at least log the error?

I had this in a previous version, but then it showed up twice here:

→ discover related assets for 1 asset(s)
x failed to connect to asset error="rpc error: code = Unknown desc = GET https://ghcr.io/v2/mondoohq/mondoo-operator/manifests/sha256-34e4bc26bf44ae1dddab394f5e9449664d6fe3a4.sig: MANIFEST_UNKNOWN: manifest unknown" asset=
x unable to connect to asset error="rpc error: code = Unknown desc = GET https://ghcr.io/v2/mondoohq/mondoo-operator/manifests/sha256-34e4bc26bf44ae1dddab394f5e9449664d6fe3a4.sig: MANIFEST_UNKNOWN: manifest unknown"
→ synchronize assets

So, I removed the logging.
