This only adds patching of the git URL for the generations section, not in the template section of the ApplicationSet. This will be patches by the Argo CD Application itself.

Hi @robinlieb thanks for the PR, and sorry for the delays in reviewing this. Generally we like to see the Zarf agent functionality tested in an end to end way. It helps us ensure that there are no regressions in the mutating web hook, and that the mutated resources work in a cluster as expected. Could you add an application set to the argocd package in examples? With how our test suite is currently structured, this will sufficiently test the webhook.

Also we should add a quick line modification to the argocd line in the init package docs that adds Argocd Application Sets

Thanks for the feedback, will update the PR with a useful example for the Argo CD Application set in the Argo CD example and update the init package docs.

Example and docs added.
