[BLOCKER] Fix in v1.19.0 for dataclass error due to triton package update (#729)

The triton package within requirements-hpu.txt got an update to version
3.2.0 today (https://pypi.org/project/triton/#history).
This breaks our current 1.19 based dockers on Gaudi 2 (probably Gaudi3
as well) and prevents vllm from running any example. (offline/online
both).
Fixing this package version to 3.1.0 solves the issue.
