Use the documented .Capabilities.KubeVersion.Version in the hpa template (#3766)

The value `.Capabilities.KubeVersion.GitVersion` is documented in Helm v2 docs - https://v2.helm.sh/docs/chart_template_guide/#built-in-objects

It seems to also work with Helm v3, but it is not documented in the docs - https://helm.sh/docs/chart_template_guide/builtin_objects/

We should stick to the officially documented values.
