While doing some work on the Piped Helm Chart, I realised that it relies on the lookup Helm function, which by default does not run when helm template is executed. This requires the --dry-run=server flag to be passed to Helm when executing.

Ideally, we are able to activate this flag only when necessary, maybe with a dryRunServer or enableServer(?) parameter in https://github.com/hall/kubenix/blob/main/lib/helm/chart2json.nix.

I don't super love the idea of using this since it could break the reproducibility Nix offers, but some charts do rely on this and are incompatible with Kubenix.
