**Describe the bug**

ApplicationSet generator parameters are being passed blank to template

**To Reproduce**

apiVersion: argoproj.io/v1alpha1
kind: ApplicationSet
metadata:
name: rhacm-policies-rollout
spec:
generators:
- list:
elements:
- environment: "dev"
phase: "phase_a"
version: "0.1.44"
syncWave: "0"
- environment: "dev"
phase: "phase_b"
version: "0.1.45"
syncWave: "-1"
- environment: "rnd"
phase: "phase_a"
version: "0.1.44"
syncWave: "0"
- environment: "rnd"
phase: "phase_b"
version: "0.1.45"
syncWave: "-1"
template:
metadata:
name: "push-policies-{{.environment}}-{{.phase}}"
annotations:
argocd.argoproj.io/sync-wave: "{{.syncWave}}"
debug-version: "{{.version}}"
spec:
project: default
source:
repoURL: "https://rmyrepo.com/nice"
targetRevision: "{{ .version }}"
chart: acm-policies-healthcheck
destination:
server: https://kubernetes.default.svc
namespace: openshift-gitops
syncPolicy:
automated:
prune: false
selfHeal: false

**Expected behavior**

Values from list parameters should be passed in template, but it is not happening

**Version**

2.13.1 (OpenShift GITOPS ARGOCD)

Start by applying the provided ApplicationSet manifest and checking the generated Application metadata and source revision; compare the list generator parameters with the template output. Trace the ApplicationSet generator and template handling in the Go controller, then add or update a regression test for list parameters. Done means environment, phase, version, and syncWave values appear in the generated Application instead of blank values.
