useHelmSecrets does not append secrets to helm template command

[aimichelle]

Expected behavior

The helm-secrets plugin allows users to pass encrypted secrets/values files to Helm. The plugin decrypts the secrets and passes the decrypted files for use in the Helm command, and is initiated by running helm secrets <usual command>. The useHelmSecrets config in Skaffold instructs skaffold to run helm with the secrets plugin.
When running skaffold run with a Helm release, I would expect skaffold to run the helm secrets template command.

Actual behavior

When running skaffold run -v DEBUG to deploy a Helm release with useHelmSecrets: true, the Helm command clearly does not contain the secrets call.

Information

• Skaffold version: v.2.8.0
• Operating system: Ubuntu 22.04.3 LTS
• Installed via: Github releases binary

Steps to reproduce the behavior

1. Add useHelmSecrets: true to a Helm release in the skaffold.yaml
2. skaffold run -f skaffold.yaml -v DEBUG
3. Inspect the helm template command, notice it does not begin with helm secrets.
