Update Python support

[dougollerenshaw]

This repo tests against Python 3.8, 3.9 and 3.10:

aind-data-access-api/.github/workflows/run_dev_tests.yml

Line 12 in 498e525

python-version: [ '3.8', '3.9', '3.10' ]

aind-data-access-api/.github/workflows/run_main_tests.yml

Line 13 in 498e525

python-version: [ '3.8', '3.9', '3.10' ]

Python 3.8 is end of life since late 2024
Python 3.9 is end of life since late 2025

Python 3.10, 3.11, 3.12 and 3.13 are all in active release

We should update testing infrastructure accordingly.

Can we explicitly drop support for 3.8 and 3.9?
