chore: migrate to pyproject.toml and hatch
The previous build process relied on `distutils` which is due to be deprecated in 3.12. Furthermore, the use of `setup.py` is now discouraged. The choice to migrate to `hatch` was made for the following reasons: - It offers a very simple management of the venv. No more need to `python -m venv .venv` and `pip install`, `hatch` handles all of that automatically when creating the virtual environment. - `hatch` supercedes `tox`, allowing for multiple python versions to be tested in a single command. - `hatch` manages the build process, and offers a nicer way to hook in a custom build process to download the `pact` standalone binaries. A minor change to the packaging of the library now places the binaries in `pact/bin` instead of `pact/bin/pact/bin`. The `constants.py` file has been accordingly updated to reflect this change in case anyone was making direct use of the binaries. While this change is rather significant, it should not affect the end user experience. Users will still be able to `pip install pact-python` from PyPI. Other than for the aforementioned, there has been no changes to the library code.
