code_signing_config_arn is conditionally set based on environments_with_signing, but the code signing config created by this module uses untrusted_artifact_on_deployment = "Enforce". With the current stack passing preprod into environments_with_signing, this will enforce signing in preprod too, which conflicts with the PR description (“sign but do not enforce”). A common approach is to either (a) only attach the config in enforced environments, or (b) make the signing policy configurable per environment (e.g., Warn vs Enforce).

I decided to enforce preprod at the same time as this PR, as the pre-requisite step of deploying the signing infrastructure has already been done
