tidb-scheduler now supports kubescheduler.config.k8s.io/v1 in tidb-operator helm charts

[makocchi-git]

What problem does this PR solve?

• tidb-scheduler crashes when deployed on Kubernetes clusters with version 1.28 or higher because kubescheduler.config.k8s.io/v1beta2 was removed from 1.28.

$ kubectl version
Client Version: v1.31.2
Kustomize Version: v5.4.2
Server Version: v1.31.4

$ kubectl get pod

• Use Capabilities.KubeVersion.Version instead of Capabilities.KubeVersion.GitVersion
  • Capabilities.KubeVersion.GitVersion was already removed in helm docs.

What is changed and how does it work?

Use kubescheduler.config.k8s.io/v1 in tidb-operator helm charts template when Kubernetes version 1.25 or higher.
(kubescheduler.config.k8s.io/v1 was GA at 1.25)
