Fix multitude of warnings

[mshafer-NI]

Justification

Currently, running ni-python-styleguide on a code base will print a lot of warnings like

.venv\Lib\site-packages\flake8_import_order\styles.py:3: 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 iter_entry_points

Upgrading to newer flake8-import-order and removing the pin on setuptools resolves this.

This also resolves #226

Pull request overview

This PR reduces runtime warnings emitted by ni-python-styleguide by updating the flake8-import-order dependency (and removing the direct setuptools pin that was needed for older flake8-import-order versions), aligning with the goal of resolving the warning noise described in the PR and addressing #226.

Changes:

• Bump flake8-import-order to 0.19.2 and drop the direct setuptools pin in pyproject.toml.
• Regenerate poetry.lock to reflect the dependency update.
• Remove the Renovate rule that previously disabled updates for flake8-import-order / setuptools.
• Adjust the “bare CLI” tests’ success assertions/output checks.
