fix(utils): close SSH client in GetKubeConfig

[ArangoGutierrez]

Summary

• Add defer func() { _ = p.Client.Close() }() after provisioner.New() in pkg/utils/kubeconfig.go
• Fixes SSH connection leak: provisioner.New() opens an SSH connection that was never closed, leaking a TCP socket and SSH multiplexer goroutines on every call to GetKubeConfig

Audit Finding

• Nit tips #4 (HIGH): SSH client leak in GetKubeConfig
