Helm docs are incorrect for argocd

Motivation

The generated README for argocd puts the argocd-apps key under upstream when it's actually a subchart of this chart. This should be a top-level key. Because of this error, the generated helm docs are incorrect. This led to a production outage for party bus on Aug 28th post-upgrade to the newest version of Big Bang

Acceptance Criteria

• All values for the argocd chart must be audited for correct placement
• argocd-apps specifically is known to be incorrect and must be moved out (outdented) of the upstream key
• The helm-docs must be regenerated
