[gcanlin]

What this PR does / why we need it?

Closes #3508.

To continuously monitor the accuracy of the Qwen3-VL-8B-Instruct model, this PR adds the corresponding configuration file to the CI.
The current accuracy is around 0.55, and gpu_memory_utilization is set to 0.5 to prevent OOM issues.

Does this PR introduce any user-facing change?

Code Review

This pull request adds a new accuracy evaluation configuration for the Qwen3-VL-8B-Instruct model. The changes are straightforward, involving the creation of a new YAML configuration file and updating the list of test configurations. My review includes one suggestion to improve file formatting by adding a newline character at the end of accuracy.txt. This change will ensure compliance with POSIX standards and prevent potential issues with various development tools.
