Buildpacks do not seem to use tagPolicy

Trying to do a standard buildpack build for Kotlin/Spring Boot:
```
apiVersion: skaffold/v4beta12
kind: Config
metadata:
name: aimia

build:
artifacts:
- image: company/aimia
context: .
sync:
auto: true
buildpacks:
builder: paketobuildpacks/builder-jammy-base
trustBuilder: true
env:
- BP_JVM_VERSION=21
- BPL_DEBUG_ENABLED=true
```

This mostly works fine, except that skaffold generates a tag I would expect, but `pack` does not use that tag:

```

If I run `pack` from the command line, this seems to work fine. The debug output from skaffold isn't helpful, as it just shows `Executing template &{envTemplate 0x140008ff320 0x140008f8730 }`
