Default chart values are not fully exported

[tvandinther]

When exporting the default values of any chart directly as shown in the example below, an incomplete default values map is rendered.

import vendored.helm.podinfo

_chart: podinfo.Chart{}
_chart.values

❯ knit render
affinity: {}
backends: []
cache: ''
extraArgs: []
extraEnvs: []
logLevel: info
nodeSelector: {}
podAnnotations: {}
podDisruptionBudget: {}
replicaCount: 1
securityContext: {}
tolerations: []
topologySpreadConstraints: []

This is because the auto-generated values KCL schema does not instantiate subschemas by default or offer a way to opt in to that behaviour. This issue is raised here: kcl-lang/kcl#1794

Upon resolution of the upstream issue, this behaviour can be fixed.
