Deprecated use of setup.py in Makefile

[Adam-D-Lewis]

I noticed deprecated use of python setup.py sdist and python setup.py bdist_wheel in the Makefile.

Seems that we should be using python -m build instead according to https://packaging.python.org/en/latest/discussions/setup-py-deprecated/.

Unfortunately it's not quite so straightforward, we will need to move to e.g. scikit-build-core so this is a longer term effort. It is more likely we will pin to a specific setup tools for the time being.
