### What this PR does / why we need it?
After some observation, I found some cases failed for timeout, just like
https://github.com/vllm-project/vllm-ascend/actions/runs/22280996034/job/64487867977#step:9:921
and
https://github.com/vllm-project/vllm-ascend/actions/runs/22315540111/job/64574590762#step:9:1809,
this may caused by the excessively long model loading time (currently we
are still loading weights from network storage), it is necessary to
adjust the timeout seconds 600s -> 1800s
