feat: deploy argocd-image-updater via Helm

Deploys ArgoCD Image Updater into the argocd-image-updater namespace.
Vault-managed secrets provide registry credentials for git.unkin.net
and an ArgoCD API token.

Prerequisites before syncing:
- Create Vault role argocd-image-updater in k8s/au/syd1
- Populate kv/service/argocd-image-updater/registry-creds (key: creds, value: <user>:<token>)
- Create ArgoCD local user image-updater and store token at kv/service/argocd-image-updater/argocd-token
