What's in this PR?

• Upgraded go from 1.19 to 1.20
• Upgraded all dependencies

Why?

To keep things up to date!

Additional context

sigs.k8s.io/controller-runtime/pkg/envtest/printer has been depreciated so I removed our single dependency on it

It looks like upgrading the controller-gen package amended all the CRDs too - I can revert this if we don't want to touch them?

We will need a new build image pushed to fix the build here:

Starting container ghcr.io/konpyutaika/docker-images/nifikop-build:1.20
  image cache not found on this host, downloading ghcr.io/konpyutaika/docker-images/nifikop-build:1.20

  Error pulling image ghcr.io/konpyutaika/docker-images/nifikop-build:1.20: Error response from daemon: manifest unknown... retrying
  image cache not found on this host, downloading ghcr.io/konpyutaika/docker-images/nifikop-build:1.20

I raised a proposal to relocate the build image into its own repo so that we can manage it separately from nifikop itself:

Either that or we add CI jobs to auto-push the build image to avoid it being a hurdle in the future and requiring manual intervention.
