Bump chartify to 0.4.2 (#1437)

To fix the issue that adhoc json patches were not working on kustomize/raw manifests.

Note that regular kustomize project was working. In other words, this only affetcts `chart: path/to/dir` combined with `jsonPatches: ...` when the `path/to/dir` points to a kustomize project or a local directory containing raw K8s manifests.

Ref #1434 (comment)
