argo-cd: new multiple sources doesn't work with helm-secrets

Checklist:

• I’ve searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
• I’ve included steps to reproduce the bug.
• I’ve pasted the output of argocd version.

Describe the bug

When using as values files in helm application with secrets, using the “secrets+age-import:///age-secret-key/keys.txt” file uri, the ref is not replaced with the file path.

To Reproduce

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: namespace-config
spec:
  project: project
  destination:
    name: in-cluster
    namespace: staging
  source:
    - repoURL: repo2
      targetRevision: main
      ref: config
    - repoURL: repo # Can point to either a Helm chart repo or a git repo.
      targetRevision: HEAD  # For Helm, this refers to the chart version.
      path: path # This has no meaning for Helm charts pulled directly from a Helm repo instead of git.
      helm:
        valueFiles:
          - values.yaml
          - $config/namespace-config/default/values.namespace.yaml
          - secrets+age-import:///age-secret-key/keys.txt?$config/namespace-config/default/secrets.namespace.yaml
          - $config/namespace-config/staging/values.namespace.yaml
          - secrets+age-import:///age-secret-key/keys.txt?$config/namespace-config/staging/secrets.namespace.yaml
      ignoreMissingValueFiles: false
  syncPolicy:
    automated: # automated sync by default retries failed attempts 5 times with following delays between attempts ( 5s, 10s, 20s, 40s, 80s ); retry controlled using `retry` field.
      prune: true # Specifies if resources should be pruned during auto-syncing ( false by default ).
      selfHeal: true # Specifies if partial app sync should be executed when resources are changed only in target Kubernetes cluster and no git change detected ( false by default ).
      allowEmpty: false # Allows deleting all application resources during automatic syncing ( false by default ).
    syncOptions:     # Sync options which modifies sync behavior
      - Validate=false # disables resource validation (equivalent to 'kubectl apply --validate=false') ( true by default ).
      - CreateNamespace=true # Namespace Auto-Creation ensures that namespace specified as the application destination exists in the destination cluster.
      - PrunePropagationPolicy=foreground # Supported policies are background, foreground and orphan.
      - PruneLast=true # Allow the ability for resource pruning to happen as a final, implicit wave of a sync operation
    # The retry feature is available since v1.7
    retry:
      limit: 5 # number of failed sync attempt retries; unlimited number of attempts if less than 0
      backoff:
        duration: 5s # the amount to back off. Default unit is seconds, but could also be a duration (e.g. "2m", "1h")
        factor: 2 # a factor to multiply the base duration after each failed retry
        maxDuration: 3m # the maximum amount of time allowed for the backoff strategy
  # RevisionHistoryLimit limits the number of items kept in the application's revision history, which is used for
  # informational purposes as well as for rollbacks to previous versions. This should only be changed in exceptional
  # circumstances. Setting to zero will store no history. This will reduce storage used. Increasing will increase the
  # space used to store the history, so we do not recommend increasing it.
  revisionHistoryLimit: 1

Expected behavior

ArgoCD should replace $config by the directory path

2.6.0-rc1 (i have no ingress on the argocd deployment so argocd version don't work)
