Supporting Python 3.12

[marcharper]

setuptools is deprecated and removed in Python 3.12, so we have to either use a third party version or change how we do packaging. Right now setup.py fails because setuptools is not available in the standard library. See #1428

IIUC we need to migrate from setup.py to pyproject.toml. But there are some choices that need to be made, e.g. which build tool. setuptools is still an option as a third party library but there are some changes.

Some options here: https://packaging.python.org/en/latest/guides/writing-pyproject-toml/

Here's a rough translation to pyproject.toml

[build-system]
requires = ["setuptools >= 61.0"]

[project.urls]
Documentation = "https://axelrod.readthedocs.org/"
Repository = "https://github.com/Axelrod-Python/Axelrod"

It doesn't handle these lines from setup.py yet:

    include_package_data=True,
    package_data={"": ["axelrod/data/*"]},
    packages=["axelrod", "axelrod.strategies", "axelrod.data"],
