LGTM — straightforward revert of a container image bump back to the previously working image.

Extended reasoning...

Overview

This PR reverts #1014, which upgraded the glm5-fp8-mi355x-sglang container image from rocm/sgl-dev:v0.5.8.post1-rocm720-mi35x-20260219 to lmsysorg/sglang:v0.5.10-rocm720-mi35x. The revert restores the prior image tag and removes the corresponding perf-changelog.yaml entry. Only two config/changelog files are touched.

Security risks

None. This is a config-only change swapping a Docker image tag; no code logic, auth, or data handling is modified.

Level of scrutiny

Low. Reverts are among the simplest and safest changes in a repo — they restore a known-good state. The diff is minimal and the intent is unambiguous.

Other factors

No bugs were found by the automated system. The only comment in the timeline is a boilerplate recipe-reminder from a bot, which is not applicable to a revert. The prior changelog entry being removed exactly matches what was added in #1014, confirming correctness.
