Only run unit and integration tests on oldest and latest python versions for macos

[amontanez24]

Problem Description

As an engineer, I'd like to see the results of CI workflows quickly so that I cna make changes or merge PRs more efficiently.

Github only allows 5 concurrent mac machines, while it allows 20 total machines. For this reason, our CI builds often get bottlenecked at the mac builds.

Expected behavior

• Only run the unit and integration workflows on python 3.8 and 3.12 for Macos
