Retracted library (k8s.io)

Hi,

It is no more possible to get and install the project as one of the library is retracted (k8s.io)

```
➔ go get github.com/aquasecurity/docker-bench
go: warning: k8s.io/client-go@v11.0.0+incompatible: retracted by module author: pre-module versions are obsolete
go: to switch to the latest unretracted version, run:
go get k8s.io/client-go@latest
```

Best regards,
hutchYy

Start by reproducing the reported `go get github.com/aquasecurity/docker-bench` command and inspect the dependency declarations for `k8s.io/client-go`. The work is done when the project can be fetched and installed without selecting the retracted version or emitting the reported warning.
