Ytt crashes in lovely-ytt

[wdonne]

Hello,

I'm using version 0.23.0 of lovely-ytt. The log of argocd-repo-server contains the following error:

Helm charts don't work with ytt as explained in https://github.com/crumbhole/argocd-lovely-plugin/blob/main/doc/ytt.md, even when you only modify the values file. So, you have the pass in the values.yaml file, but that is inconvenient when propagating the plugin through a tree of "app of apps" recursively.

Can you fix the documentation? The lovely authors don't use ytt.
