Issue:
Incorrect generation of vmagent config from VMScrapeConfig (kubernetesSDConfigs/attach_metadata)
```
apiVersion: operator.victoriametrics.com/v1beta1
kind: VMScrapeConfig
metadata:
  name: pods
spec:
  kubernetesSDConfigs:
  - attach_metadata:
      node: true
    role: pod
```

and incorrect result in `/etc/vmagent/config_out/vmagent.env.yaml`:
```
- job_name: scrapeConfig/vm-stack/pods
  kubernetes_sd_configs:
  - role: pod
    attach_metadata: true
```

should be:
```
- job_name: scrapeConfig/vm-stack/pods
  kubernetes_sd_configs:
  - role: pod
    attach_metadata:
      node: true
```

Version: `victoriametrics/operator:v0.60.2`
