docs: remove manual kubeScheduler image tag specification

[DSFans2014]

The Kubernetes version is automatically detected by Helm during installation and does not need to be manually specified.

fix Project-HAMi/HAMi#1991

Summary by CodeRabbit

• Documentation
  • Updated the Helm install guide to include a complete baseline install command after refreshing the Helm repository.
  • Clarified the setup flow so users can run a plain install first, then follow the version-specific example when needed.
  • Applied the same documentation update across all supported language and versioned guides.

📝 Walkthrough

Walkthrough

This PR updates Helm deployment instructions across the main docs, versioned docs (v2.7.0, v2.8.0, v2.9.0), and their zh i18n translations. It adds a baseline helm install hami hami-charts/hami -n kube-system command and, in v2.7.0, removes an incorrect scheduler.kubeScheduler.imageTag parameter usage.

Poem

A hop, a skip, a helm install line,
The docs now match the cluster fine.
No more imageTag gone astray,
Just helm install to save the day.
🐇 Thump thump — ship it, hooray!
