release-testing (#889)

* make script shebangs more flexible

* move location of python tests

This change allows us to run the test suite against a release candidate
hosted on test.pypi.org.

```
pip install --extra-index-url https://test.pypi.org/simple/ datafusion==40.0.0

pytest --import-mode=importlib python/tests
```

* add documentation for testing against release candidate

* add dev script for cleaning maturin build artifacts

* update ruff lint config for new test location
