Pyluwen: Add "version" to pyproject.toml

Maturin made a change to come inline more specifically with
pyproject.toml spec, unfortunately it's not a "backwards compatible"
change and was done with little fanfare or warning, and immediately
caused breakage outside distro's more plodding versions.

Maturin Issue: PyO3/maturin#2390
pyproject.toml spec: https://packaging.python.org/en/latest/specifications/pyproject-toml/#dynamic

change in Maturin committed here:

PyO3/maturin#2391

This commit superceeds the luwen PR here:

tenstorrent#11

as that sets an explicit version, and we don't want that as it adds more
sources of truth on the version (seriously there should be 1, and only
1).
