Review Comment:
I am not sure why the editable mode is required but otherwise it fails
importing `pyarrow.lib`. I have been able to validate on my local build tree
that without the editable mode the cython compiled files aren't available
there, I should investigate further. Those files aren't there without it, I
should investigate where are those being installed because they are being
generated:
```
python/pyarrow/lib.cpython-310-x86_64-linux-gnu.so
python/pyarrow/lib.cpython-38-x86_64-linux-gnu.so
```
as per the `--pyargs pyarrow` I just copied the same command we use for
testing on `python_test.sh` when I was debugging, I can probably revert back
this change.
