pin setuptools<81 to resolve opentelemetry warning

[eliteprox]

This change addresses a warning from opentelemetry-sdk package which is a dependency of comfyui:
/workspace/miniconda3/envs/comfystream/lib/python3.12/site-packages/opentelemetry/instrumentation/dependencies.py:4: UserWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html. The pkg_resources package is slated for removal as early as 2025-11-30. Refrain from using this package or pin to Setuptools<81.

This is resolved in a newer version (v0.49b1) according to open-telemetry/opentelemetry-python-contrib#2871 (comment)), however ComfyUI installs the older version by default, so we should pin setuptools for now to avoid issues
