[None][docs] retarget moved performance doc URLs in tech blogs

[imitater-dou]

Summary

Retarget three tech-blog absolute links that still pointed at the removed docs/source/performance/ tree:

• blog04 → docs/source/developer-guide/perf-benchmarking.md#preparing-a-dataset
• blog08 → docs/source/developer-guide/perf-analysis.md
• blog09 → docs/source/legacy/performance/performance-tuning-guide/tuning-max-batch-size-and-max-num-tokens.md

Test plan

• Confirmed old paths 404 on main
• Confirmed new paths exist; blog04 anchor #preparing-a-dataset present
• Docs-only; no code/runtime changes

Dev Engineer Review

The change updates three obsolete documentation links in tech blogs. No source code, APIs, configuration, or runtime behavior changed. The replacement paths and blog04 anchor exist.

QA Engineer Review

No test changes.

Per-File QA Perspective

• blog04_Scaling_Expert_Parallelism_in_TensorRT-LLM.md: Documentation-only link change. Verify the dataset-preparation link opens the intended section.
• blog08_Scaling_Expert_Parallelism_in_TensorRT-LLM_part2.md: Documentation-only link change. Verify the performance-analysis link resolves correctly.
• blog09_Deploying_GPT_OSS_on_TRTLLM.md: Documentation-only link change. Verify the performance-tuning guide link resolves correctly.

Walkthrough

Three technical blog links now point to current documentation paths for dataset preparation, performance analysis, and CUDA out-of-memory guidance.

Changes

Documentation link updates

Layer / File(s)	Summary
Update technical blog references docs/source/blogs/tech_blog/blog04_Scaling_Expert_Parallelism_in_TensorRT-LLM.md, docs/source/blogs/tech_blog/blog08_Scaling_Expert_Parallelism_in_TensorRT-LLM_part2.md, docs/source/blogs/tech_blog/blog09_Deploying_GPT_OSS_on_TRTLLM.md	Updated three links to current developer or performance-tuning documentation paths.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: ⚪ Minimal · up to f6c99

The technical blog links now direct readers to the current dataset-preparation, performance-analysis, and memory-tuning documentation. The updated targets are present and relevant, with no runtime or deployment impact.

Verified locally: all three targets exist on main and perf-benchmarking.md:135 provides the #preparing-a-dataset anchor. One leftover from the same doc move, if you want it in scope: .github/CODEOWNERS:195 still lists /docs/source/performance/perf-benchmarking.md, so @NVIDIA/trt-llm-perf-devs no longer gets auto-review on the file at its new path. The docs/source/performance/ references in release-notes.md are historical and should stay as-is.
