Add support for Python v3.13

Issues

• Poetry, requires g++ for building non-available msgpack wheel
• No Python v3.13 wheels from pendulum. The build requires cargo in the path for building the non-available wheel: Rust v1.63 installed from Debian 12 doesn’t seem to support RFC 3137 let…else.

• Actually, I can’t release Silkaj with official Py3.13 support, since installing it requires to have rust toolchain in the PATH in order to build pendulum which does not have Py3.13 pre-built wheels.
  • Think about getting rid of pendulum. Alternative? (Use and introduce a better date utility than da... (#251 - closed)) Arrow?

Python pre-releases

• Set up v3.13 test job
  • With allow_failure: true, to allow tests to fail

Python stable release

• Handle deprecation warning and breaking features:
  • Follow-up in: duniterpy#208 (comment 44803)

Exception ignored in: <http.client.HTTPResponse object at 0x7f8ddda7f250>
Traceback (most recent call last):

• Remove allow_failure: true, now on the tests should pass
• Switch Silkaj images builds to v3.13: once Pendulum provides 3.13 wheels, and rust toolchain is removed

CI default image switch approach change

• Move coverage to v3.13 job
• Set default container used by jobs to v3.13

Changing approach: keeping default image on 3.12 for pre-commit jobs, all tests and coverage generation. I think that’s ok, to keep them on to-be EOL Python version. Advantages: No need to synchronise git and pre-commit package install/uninstall among Silkaj, DuniterPy, and docker/python3/poetry#10 repositories. Also, solves the issue about still maintaining DuniterPy, which is uncertain. Less efforts spent on this topic, more onto Silkaj development. Once Py3.12 reaches EOL in Oct 2028 or before, move default version to latest stable Python version image.
