The purpose and format of `values-global.yaml` is not documented

[adelton]

Reading https://validatedpatterns.io/patterns/multicloud-gitops/mcg-getting-started/, there are steps like

vi values-global.yaml

git add values-global.yaml

git commit values-global.yaml

there. Content of that file is in turn

---
global:
  pattern: multicloud-gitops

  options:
    useCSV: false
    syncPolicy: Automatic
    installPlanApproval: Automatic

main:
  clusterGroupName: hub

  multiSourceConfig:
    enabled: true

However, it is not clear what CSV that useCSV is about, what syncing and installation that syncPolicy and installPlanApproval, or what the clusterGroupName value is for and what happens if any of those values get changed.

If there is something that the user following the https://validatedpatterns.io/patterns/multicloud-gitops/mcg-getting-started/ guidance should look for and change, it should be clearly documented.

If the file should be left as it is because for this pattern no changes are needed, that vi values-global.yaml step likely should not be there at all.
