Use go 1.21

[jsirianni]

Description of Changes

We should be on the latest Go version to ensure we are receiving security fixes for the standard lib.

Switching to Go required that we update some dependencies

• Lichen license scanner
• Zap logger and it's dependencies
• k8s dependencies
  • Removed ClusterName logic*
• Run windows tests without cgo, they were failing for an unknown reason. The binary we ship is cross compiled.

* K8s cluster name was removed from the SDK / Client packages for Kubernetes. I would be surprised if it was working before, because k8s does not have the concept of cluster name internally.

Please check that the PR fulfills these requirements

• Tests for the changes have been added (for bug fixes / features)
• Docs have been added / updated (for bug fixes / features)
• CI passes
