In Python 3.12, calling `python setup.py` to create wheels is deprecated;
instead, one should use a "standard-based tool" (whatever that means),
like the `build` package from PyPA.
Therefore, instead of calling `setup.py bdist_wheel`, we use `python -m
build`, which is the recommended replacement for it (as mentioned here:
https://blog.ganssle.io/articles/2021/10/setup-py-deprecated.html#summary).
Fixes #2696.
