fix: ensure the constraint file is followed also for setuptools

Currently, when the venv is installed or updated, we attempt to
automatically update pip and setuptools within the venv. Unfortunately,
the setuptools package is installed or updated without adhering to the
constraints file, which restricts the setuptools version due to
pypa/setuptools#4480. Resolve this issue by
applying the constraints file to the installation and update of both pip
and setuptools.
