Upgrade our arkouda python version

[reviewed by @bmcdonald3]

Switch from python 3.7 to 3.9 since Arkouda now requires at least 3.8
(Bears-R-Us/arkouda#1487). Note that I wanted to use a newer version do
limit when we have to do the next upgrade, but I didn't go with 3.10
since spack is still defaulting to 3.9.

Also note that I added a setup_python_arkouda wrapper so that we don't
have to change our testing and dev scripts the next time we have to
upgrade.
