[fix] swap the dash with an underscore for the karpenter CRD chart since chart-releaser doesn't seem to like the dash in the chart name

[AshleyDumaine]

What this PR does / why we need it: The chart-releaser (which the chart-releaser-action uses) doesn't seem to play nicely with charts that have a dash in the name for trying to extract the name and version: https://github.com/helm/chart-releaser/blob/v1.7.0/pkg/releaser/releaser.go#L253-L256
