Python 3.9 is now Qiskit minimum level supported

[woodsp-ibm]

Qiskit will drop Python 3.8 support with the 1.3.0 release. A PR, linked below, to bump the minimum level was just merged to Qiskit main yesterday (10th Sep 2024) and as of last night one of the tests against main is now failing due to this since the tests are at the min and max levels algorithms here supports.

• Raise minimum python version to 3.9 Qiskit/qiskit#12910

While the main CI builds which test against stable continue to work, and should do so even after 1.3.0 releases as it will pull in an older version that still has 3.8 support, at some point algorithms should change its min level and CI over to 3.9 too with the upcoming EOL of 3.8.
