introduce python 3.12 support

[williballenthin]

python 3.12 was introduced Oct 2, 2023: https://www.python.org/downloads/release/python-3120/

update the GH action workflows to invoke python 3.12 instead of 3.11, and add 3.12 to our wide matrix of tested python versions on linux.

python-flirt will require a new release with python 3.12 support, too.

Thank you for the information. Fedora offers the option to install and use 3.11 side-by-side with 3.12 (or I can install it in the venv) so I will do that.

can i direct update the version of python 3.11 to 3.12 in github workflows and matrix.

python-flirt will require a new release with python 3.12 support, too.

@EmperialX this needs to be done before the matrix is changed or the installation will fail due to missing dependencies

If I'm not mistaken, python-flirt now supports Python 3.12 since version 0.8.9 (2024-03-09?)

Problem is rather that capa depends on viv-sect[flirt] 0.7.9 (latest release as of today) that requires python-flirt 0.8.6, which does not support Python 3.12. Even the latest commit on viv-sect (unreleased) requires python-flirst 0.8.8 which is not enough.

I just created that issue: williballenthin/viv-utils#149

capa will still need to update its dependencies once there is a new viv-utils release, so the current issue is still relevant.
