Problem: Archivematica and related repositories still support Python 3.8

[replaceafill]

Expected behaviour

All Archivematica related components written in Python run only on supported Python versions.

Current behaviour

All the Archivematica related components have Python 3.8 as their lowest supported version, but 3.8 reached its end of life on 2024-10-07.

Many dependencies no longer support 3.8, so we have to pin them to outdated versions, which can cause security risks and make future upgrades harder.
