docs(core-concepts): add GPU virtualization principles page

[rootsongjc]

Add a comprehensive GPU virtualization documentation page covering:

• Kubernetes GPU scheduling fundamentals (Device Plugin, DRA)
• HAMi virtual GPU scheduling architecture and workflow
• Device injection and CUDA API interception details
• Scheduling strategy explanation (binpack/spread)

The page is added to both English and Chinese docs under Core Concepts, with PlantUML sequence diagrams exported as SVG images for each language.

This document has been rewritten based on the content of @togettoyou https://github.com/togettoyou/kubernetes-src-notes/blob/main/content/addons/hami.md

hey @rootsongjc, i found an issue. the docs reference ./architecture.md in two places but that file isn't included in this PR:

• gpu-virtualization.md line 248
• introduction.md line 43

looks like you have the diagrams (hami-architecture.plantuml, svg files) but the actual markdown doc is missing. users will get 404s when they click those links.

should i create that file or do you want to handle it?

hey!

Docs migration from HAMi repo:
checked what needs to be migrated from https://github.com/Project-HAMi/HAMi/tree/master/docs

most stuff is already on website, just converted to docusaurus format:
-benchmark, config, dashboard, offline-install, release notes
-all device docs (nvidia, cambricon, hygon, etc)
-missing: scheduler-event-log.md (troubleshooting guide), how-to-profiling-scheduler.md (dev debugging), general-technical-review.md

recommendations:
-verify scheduler-event-log and profiling docs aren't already somewhere on site
-if they're really missing, add them under /docs/troubleshooting/ and /docs/developers/
-use docusaurus frontmatter format like the rest of the docs
-update sidebars.js to include them

I checked the docs do exist, and this PR only render on the next version. Once this version is OK , I will add the them to the current version (v2.8.0).
