Helm chartPath template doesn't render for `deploy` command

### Expected behavior

The value in the `.deploy.helm.releases.0.chartPath` always passes through template rendering

### Actual behavior

When running locally `skaffold deploy` correctly renders the value out of my local environment into the `helm` install command. When the same command and same version of skaffold run in our CD pipeline (Azure Devops Pipeline), the template text itself is passed to helm.

### Information

- Skaffold version: v2.6.0
- Operating system: Local - WSL 2 Ubuntu 22.04 / CD pipeline - Ubuntu 22.04 based image
- Installed via: Downloaded amd64 binary
- Contents of skaffold.yaml:

```yaml
apiVersion: skaffold/v2beta19
kind: Config
deploy:
helm:
releases:
- name: calendar
chartPath: '{{.HELM_REPO}}/service'
namespace: calendar
profiles:
- name: dev
patches:
- op: replace
path: /deploy/helm/releases/0/namespace
value: dev-calendar
```

### Steps to reproduce the behavior
1. `skaffold -v=debug deploy -t -p dev -f skaffold-aws.yaml --kubeconfig ...`

Logs have been redacted to pull most of the environment out, but all the expected image information is there.

Running locally:
