Update CI's

[scott-huberty]

Closes #232

1. Bump Github Actions (GHA) MacOS Intel Runner to Arm64 (MacOS 14 Sonoma). GHA Has dropped support for Intel Macs.
2. Bump checkout
   3. Bump the Version of Python we use in the CI's from 3.9 to 3.10 (Python 3.9 hit its End of life this month: https://endoflife.date/python )
3. Configure our CI to run our test suite every night (So we get notified of breaking upstream changes even if we go long periods between PR's).

Let's see if anything else has broken since the last PR...

Woohoo!! Everything is still passing. I guess we wrote some robust code and robust tests : )
