Describe the bug

argocd appset get command doesn't show multiple sources details if your appset manifest consists of multiple sources.

To Reproduce

1. Generate a appset that consists of multiple sources, something like

   apiVersion: argoproj.io/v1alpha1
   kind: ApplicationSet
   metadata:
   name: color-applicationset-multi-source
   namespace: argocd
   spec:
   generators:
   - list:
       elements:
         - namespace: dev
         - namespace: test
         - namespace: uat
   template:
   metadata:
     name: '{{namespace}}-color-appsssss'
   spec:
     project: default
     sources:
       - repoURL: https://github.com/argoproj/argocd-example-apps.git
         targetRevision: HEAD
         path: apps
       - repoURL: https://github.com/argoproj/argocd-example-apps.git
         path: guestbook
         targetRevision: HEAD
     destination:
       server: https://kubernetes.default.svc
       namespace: '{{namespace}}'

2. Get the appset details using the following command

   argocd appset get color-applicationset-multi-source

3. Notice that inspite of setting multiple sources, only the first source gets printed.

Expected behavior

All the sources should get printed.
