UserWarnings due to `pkg_resources`

[dataflake]

Describe the bug

Running scripts with bin/zopeinstance emits warnings because pkg_resources is used:

/opt/zope/.eggs/v5/plone.recipe.zope2instance-8.0.1-py3.11-linux-x86_64.egg/plone/recipe/zope2instance/ctl.py:30:
  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 very annoying for everyone who runs recurring scripts as cron jobs. The warnings output will trigger emails on every run.

To Reproduce

Create a virtual environment with setuptools<81 and zc.buildout>=5.1.1 and build an instance with plone.recipe.zope2instance. Use the instance control script.

Expected behavior

No warnings.
