chore: Upgrade Spectrum and go-containerregistry

[astefanutti]

This PR upgrades Spectrum (the default build strategy on vanilla Kubernetes) to the latest version, that contains an upgraded patched version of go-containerregistry, whose fork is now hosted at https://github.com/container-tools/go-containerregistry.

That new version of go-containerregistry has seen quite a lot of useful improvements compared to the current version.

FWIW, on my laptop, with Minikube, the first build (with dependencies download) of a typical REST Camel K integration takes 25s:

$ kubectl get builds.camel.apache.org
NAME                       PHASE       AGE   STARTED   DURATION        ATTEMPTS
kit-c6f3jaiks20t8nm2oi8g   Succeeded   45s   45s       25.512306317s  

While subsequent builds take around 16s:

$ kubectl get builds.camel.apache.org
NAME                       PHASE       AGE   STARTED   DURATION        ATTEMPTS
kit-c6f3k6qks20t8nm2oi90   Succeeded   31s   31s       16.149875583s 

Which provides a fairly decent user experience, performance wise.

Release Note
