Update HPA for authservice

Issue: #67 (closed)

According to the issue here:

A version number with a dash following the .. version fields is marked as a pre-release. Pre-releases are excluded from general semantic version lookups unless the constraint includes a pre-release identifier to the constraint.

Therefore, updated the following so customers using BigBang on AWS-EKS would not get impacted.

{{- if (semverCompare ">=1.23" .Capabilities.KubeVersion.GitVersion) }}

to

{{- if .Capabilities.APIVersions.Has "autoscaling/v2" -}}
