Add Python 3.13 support in CI

[PaTara43]

It seems like the runners don't automatically use Python 3.13, but htere is a way to add support manually (e.g. this and this). Are there any limitations on adding that? If not, is it possible to do so? Same goes for https://github.com/polkascan/py-ed25519-bindings and https://github.com/polkascan/py-sr25519-bindings
Thanks!

p.s. perhaps, the find-interpreter arg may be kept, but python version added on the previous step (source)

steps:
- uses: actions/checkout@v4
- uses: actions/setup-python@v5
  with:
    python-version: '>=3.9 <3.14'
- run: python my_script.py

I also suspect the PyO3 version is a bit outdated, which prevents compiling for 3.13. I will have to look into that as well.

At least https://github.com/polkascan/py-sr25519-bindings needs some refactoring because of deprecated PyO3 version

Updated PyO3 and released, not many code changes needed: https://pypi.org/project/py-bip39-bindings/0.2.0/

https://github.com/polkascan/py-sr25519-bindings is not that easy unfortunately, too outdated code. More thorough rework is required there.

Awesome news! We'll check it out tommorrow. Any thoughts on https://github.com/polkascan/py-ed25519-bindings?

Thank you!

Thank you!

You mean https://github.com/polkascan/py-ed25519-zebra-bindings/ ? That was also easy to upgrade, released: https://github.com/polkascan/py-ed25519-zebra-bindings/releases/tag/v1.2.0

Hey! Just to let you know, it works perfect on Ubuntu 24.04 server with Python 3.13 on RPi 4
