Describe the bug

badge.go does not take into account multi-source applications when determining the revision to display on a badge. It only extracts the value from app.Status.OperationState.SyncResult.Revision, leaving app.Status.OperationState.SyncResult.Revisions behind.

Example multi-source application object dumped via the API:

To Reproduce

Crate a multi-source application and generate a the badge passing revision=true. No revision is added.

Expected behavior

Revisions from sources are added to the badge.
