Description of problem:

When using the argocd plugin for developer hub, the plugin can load the application from argocd successful, but when loading the revision metadata, the revisionID is undefined and the api call returns a http code 500

{"level":"\u001b[32minfo\u001b[39m","message":"[04/Feb/2025:09:34:54 +0000] \"GET /api/argocd/argoInstance/test/applications/name/my-test-app/revisions/undefined/metadata HTTP/1.1\" 500 232 

Issue only happens argocd application have "revisions" (more than 1 revision id) attribute instead of "revision"  like below

"history": [{
     ...
     "revisions": [
         "abcdef",
         "12345"
     ],

It works fine with below attribute.

history:
    - deployStartedAt: '2025-02-06T14:57:33Z'
      deployedAt: '2025-02-06T14:57:36Z'
      id: 0
      initiatedBy:
        username: admin
      revision: abcdef

Prerequisites (if any, like setup, operators/versions):

Steps to Reproduce

1. Configure Argocd plugin in RHDH to fetch any application with multiple revisions. 
2. Altough the application is loaded correctly, the revision details are not fetched.

Actual results: Revision details is fetched as undefined.

Expected results: Revision detail needs to be fetched correctly

Reproducibility (Always/Intermittent/Only Once): Always

Additional info (Such as Logs, Screenshots, etc):

Plugin code seems to be looking for singular revision attribute, it's considering argocd multiple source scenario.
