helm gets passed quoted values wrong

### Expected behavior

Quoted values should be passed to helm as quoted.

```
env:
value: "true"
```

### Actual behavior

`--set api.deployment.sidecars[0].env[3].value=true`

### Information

- Skaffold version: v2.7.1
- Operating system: Ubuntu 22.04
- Installed via: apt
- Contents of skaffold.yaml:

```yaml
manifests:
helm:
releases:
- name: codecov
chartPath: helm-charts/codecov
namespace: codecov
setValues:
api.deployment.sidecars[0].env[1].name: CSQL_PROXY_HEALTH_CHECK
api.deployment.sidecars[0].env[1].value: "true"
api.deployment.sidecars[0].env[2].name: CSQL_PROXY_PROMETHEUS
api.deployment.sidecars[0].env[2].value: "true"
api.deployment.sidecars[0].env[3].name: CSQL_PROXY_STRUCTURED_LOGS
api.deployment.sidecars[0].env[3].value: "true"
```

### Steps to reproduce the behavior

1. `skaffold render`
