feat(helm): Support for Helm Chart.yaml appVersion field defaulting t…

…o project version

Adds the appVersion field to the HelmConfig class so that it can be propagated from
the Helm plugin configuration and the `jkube.helm.appVersion` property.

The field is now provided by default with the current project version
(i.e. by default Chart.yaml appVersion and version default to the same value)
