Fixes #1372
Add Python version 3.13 to matrix.

Python Rust binding maximum supported version (3.12)

error: the configured Python interpreter version (3.13) is newer than PyO3's maximum supported version (3.12)

@JE-Chen Thanks for checking. It looks like Py3O is already at 3.13: PyO3/pyo3#4636 I was hoping that maybe bumping the Poetry build might fix it #1379. Could you rebase? Otherwise we have to track which dependency is still locked at this older version of Py3O.

Done

Same error.

Currently, we are using pyo3 v0.20.3. I think only versions of pyo3 v0.21 or newer support Python 3.13.
Some dependencies require pyo3 v0.20.3, but I don't find pyo3 listed in the Poetry requirements.

@JE-Chen I think it pulls pyo3 in when it can't find pre-build wheels for a combination of the Python version and architecture.

Note: This error originates from the build backend, and is likely not a problem with poetry but with cramjam (2.8.3) not supporting PEP 517 builds. You can verify this by running 'pip wheel --no-cache-dir --use-pep517 "cramjam (==2.8.3)"'.

Looks like we're still pinning on an older version of cramjam, as 2.9.1 is out already: https://pypi.org/project/cramjam/

Fixing conflicts to see where we are with 3.13 :)
