Since the HorizontalPodAutoscaler v2beta2 is deprecated since 1.23, I have taken the shortcut and replaced the group version.

Hi,

I suggest to use the following to be backward compatible:

apiVersion: {{ ternary "autoscaling/v2" "autoscaling/v2beta2" (.Capabilities.APIVersions.Has "autoscaling/v2") }}

[Tanemahuta]

Downside: some IDEs (e.g. IntelliJ IDEA in my case) will not properly recognize GVK
If you plan to use beta features and support previous API versions, you might want to create a helper for this.
Pushed a new commit.
