Update docs to reflect correct flag

[jake-luna-sada]

Hello, going through some of the documentation and testing things out I noticed there is a typo here https://console.mondoo.com/space/integrations/add/mondoo/setup?spaceId=pedantic-kepler-689646

In particular cnspec scan k8s --namespace where is should be cnspec scan k8s --namespaces. Though personal opinion it should be --namespace to match existing kubectl commands

Thanks for the report @Jluna-sada. I cut a PR to fix this.
