Error when bumping protobuf from 3.20.1 to 3.20.2 - setuptools

[Glen]

Hi,

Why does this change come with a dependency on setuptools as seen in the commit?

[[package]]
name = "setuptools"
version = "65.3.0"
description = "Easily download, build, install, upgrade, and uninstall Python packages"
category = "main"
optional = false
python-versions = ">=3.7"

Then, setuptools is removed...
Installing dependencies from lock file
Package operations: 41 installs, 7 updates, 1 removal
  • Removing setuptools (65.3.0)

I get this error when running my dependabot created PR for the protobuf 3.20.2 change:
