Update qwen3.5-bf16-mi355x-sglang and mtp SGLang ROCm image to v0.5.12-rocm720-mi35x-20260517 (#1443)

* Update qwen3.5-bf16-mi355x-sglang and mtp SGLang ROCm image to v0.5.12-rocm720-mi35x-20260517

Ref #1154

Co-authored-by: Klaud Cold <Klaud-Cold@users.noreply.github.com>

* fix: use sglang v0.5.12 release tag instead of dated nightly

Drops the -20260517 nightly suffix so the recipe uses the
lmsysorg/sglang-rocm:v0.5.12-rocm720-mi35x release tag rather than
a date-pinned nightly build.

* chore: update perf-changelog description to v0.5.12 release tag (drop nightly suffix)

* Revert to dated nightly tag: v0.5.12-rocm720-mi35x-20260517

Docker Hub does not publish a clean lmsysorg/sglang-rocm:v0.5.12-rocm720-mi35x
release tag — only the dated nightly variant. The earlier switch to the
un-suffixed tag was a mistake (caused 'manifest not found' on every job).

Restoring the dated nightly tag that does exist.
