Missing distutils in Python 3.12

When you run an application using kubeconfig on a Python 3.12 venv, then you run into an error:

```
ModuleNotFoundError: No module named 'distutils'
```

It seems as if the distutils package has been removed in Python 3.12 and needs to be installed manually:

```
pip3 install setuptools
```
