helmfile: fixup for argocd-config 1.0.8 (#1847)

Unfortunately 1.0.8 was mistakenly configured to use
https://github.com/wbstack/charts.git rather than
https://wbstack.github.io/charts and therefore
wasn't correctly parsing the chart without a path.
1.0.9 is a fixup for this that uses the correct
repoUrl
