Drop support for python 3.8 & add 3.13

[ItsDrike]

This PR drops support for the now EOL Python 3.8 (since 2024-09-06). Additionally, since we haven't done so yet, it also adds support for python 3.13 - moving the latest CI version & adding it to tox versions.

Additionally, this also performs some housekeeping tasks:

• Remove deprecated ANN1XX ignores, these rules were deprecated by ruff and aren't enabled by default anymore, no need to be disabling them.
• Run ruff format, which is apparently failing after this update, even though ruff itself wasn't updated here. Perhaps it's bacause the changed pythonVersion config value for ruff, though the suggested format change would work produce a working python syntax for 3.8 too, so I'm not sure why it only failed here.
• Update cffi dependency, as the current version fails to build on MacOS with Python 3.13
• Update requests dependency, as the currently installed version: 2.32.0 was marked as yanked, due to CVE-2024-35195.
• Bump down the pythonVersion config value of pyright to the oldest supported version (3.9), for some reason, this was set to 3.10 - I think this was done because pyright didn't support checking for __future__.annotations before, and we decided we wanted to be able to utilize the newer typing syntax with it, so we used a more recent version to avoid the errors. However, since pyright does support __future__.annotations now, this can be dropped back down.

Note: #928 is currently blocked by this PR, as poetry 2.0 has dropped support for py 3.8
