UserWarning: pkg_resources is deprecated as an API

[ajjamieson]

Describe the bug

When running az network bastion ssh commands we recieve

/.azure/cliextensions/bastion/azext_bastion/custom.py:107: 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.
from pkg_resources import parse_version

This warning breaks our tooling, can the warning be silenced or the pkg_resource dependency be removed?

We've tried

1. export PYTHONWARNINGS=ignore
2. --only-show-errors
3. pip install setuptools==80.8.0 --force-reinstall

Ref (was fixed on other parts of az cli):
Azure/azure-cli#31591

Versions:
azure-cli 2.75.0
core 2.75.0
telemetry 1.1.0
Extensions:
azure-devops 1.0.2
bastion 1.4.1
ssh 2.0.6

@yonzhan, our company has a large number of developers experiencing this warning. What is the recommended course of action?

If we do not get a response in the next couple weeks, I will be submitting a ticket via azure portal to escalate.

We are experiencing it when using az artifacts. We predominantly use windows and almost all machines have the latest version of the extension and az cli.
