Values Schema cannot be validated in Air-Gapped Environment

[Avarei]

I am currently trying to deploy this chart in an air-gapped environment but the values.schema.json contains external internet references as mentioned in #92.

Due to the air-gapped environment I cannot even resolve the hostname:

Error: values don't meet the specifications of the schema(s) in the following chart(s):
backstage:
Get "https://kubernetesjsonschema.dev/master/_definitions.json": dial tcp: lookup kubernetesjsonschema.dev on x.x.x.x:53: no such host

To my knowledge there is currently no way to skip the schema validation. helm/helm#10398

My current workaround is to remove the values.schema.json and repackage the chart in my environment.

I think ideally the Helm chart should be fully self contained.
