Running `func kubernetes deploy...` only creates secret with V4 model

This is with the Node.js runtime V4 model
I made a repo to reproduce the issue here -> https://github.com/krackergraham/az-func-k8s-deploy-error

How to reproduce
1. `func init --docker --worker-runtime node --language typescript`
1. `func new --name httpTrigger --template "HTTP trigger" --authlevel "anonymous"`
1. `func kubernetes deploy --name myfunc --namespace --registry --write-configs`
1. or with `--dry-run` instead of `--write-configs`

Tooling
```
➜ func version
4.0.5455
```

```
➜ az version
{
"azure-cli": "2.56.0",
"azure-cli-core": "2.56.0",
"azure-cli-telemetry": "1.1.0",
"extensions": {}
}
```

Possibly relates to #3381 #3579

Reproduce the issue with the commands in the report, using the linked repository and comparing --write-configs with --dry-run for the Node.js V4 model. No source files or tests are named, so trace the func kubernetes deploy entry point and determine why the generated output contains only a secret; done means the deployment configuration is generated as expected.
