docs(get-started): add a page for choosing between HAMi, HAMi-DRA, Volcano vGPU and KAI

[mesutoezdil]

What type of PR is this?

/kind documentation

What this PR does / why we need it:

#689 asks for a decision page and a capability matrix. This is both on one page, placed first under Get Started so readers choose before they reach an install guide. It answers HAMi against HAMi-DRA from the three prerequisites, then explains that HAMi, Volcano vGPU and KAI are not three answers to the same question since all three rely on HAMi-core for isolation and only the scheduler differs. Every claim is taken from a page already in this repo and linked from the table.

Which issue(s) this PR fixes:

Part of #689

Checklist:

• npm run lint and npm run format:check pass
• npm run build succeeds for both en and zh
• Chinese translation updated if English docs changed (or noted why not)
• Commits are signed off (git commit -s)

📝 Walkthrough

Walkthrough

Added English and Chinese setup-selection guides that compare HAMi deployment options, scheduler integrations, prerequisites, and device plugin ownership. Added the new guide to the Get Started sidebar.

Changes

Setup Selection Documentation

Layer / File(s)	Summary
Setup comparison guide docs/get-started/choose-your-setup.md, i18n/zh/docusaurus-plugin-content-docs/current/get-started/choose-your-setup.md	Added setup-selection guidance for HAMi, HAMi-DRA, Volcano vGPU, and KAI Scheduler. The guides document prerequisites, allocation paths, scheduling, isolation, supported devices, installation, and device plugin ownership.
Get Started navigation sidebars.js	Added the setup-selection guide before the deployment and verification pages.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟡 Moderate · up to d98ca

The new chooser page currently contains a platform-support mismatch and incomplete resource guidance, which could lead users to select an unsupported Volcano vGPU path or miss a valid HAMi-DRA resource option. Merge should wait for these bounded documentation fixes.
