openedx/ecommerce and openedx/ecommerce-worker Python 3.12 upgrade

[DawoudSheraz]

As mentioned on https://discuss.openedx.org/t/these-idas-will-not-be-upgraded-to-python-3-11-by-redwood/12755, ecommerce and ecommerce-worker are not prioritized for Python 3.11/3.12 upgrades and are free for community to pick them up. Since these are important repositories and their upgrades are blocking tutor-ecommerce upgrade (https://github.com/overhangio/tutor-ecommerce/issues/68), Edly can take a dig at upgrading them. A note that these upgrade will be backwards compatible with 3.8.
