fix(argocd): add baseline project and application

- Add `argocd-apps` HelmChart to deploy baseline project and application
- Define `baseline` project with source repos, destinations, and cluster resource whitelist
- Define `baseline` application with source, destination, and sync policy

ArgoCD v5.0 removes support for the parameters
server.additionalApplications and server.additionalProjects.
Parameters are moved to argocd-apps.
