virtual enviornment: failed building wheel for pyarrow

[dshaaban01]

I nuked my build directory and my virtual environment (long story). I followed the steps to rebuild them - at this line I got an error:

python3 -m pip install -r ${SUBSTRAIT_MLIR_SOURCE_DIR}/requirements.txt

Because the virtual environment isn't working, CMAKE cannot run.

interestingly, pyarrow was one of the 2 tests that always failed no matter what (from first installation some months ago - I think I mentioned this to @ingomueller-net).

Anyways, I will try to fix it now, but filing an issues in case I cannot / for us to revisit in future if needed.

Turns out this is due to an incompatibility with python 3.13.0!

This website shows that there are no binaries for arm 64 macOS python 3.13.0.

I changed the version of my python to 3.12.0 and that fixed it, using these steps
