Build, test and publish Python 3.13 wheels to PyPI

[EwoutH]

Python 3.13.0 is now in release candidate phase, which makes it ABI stable and Python 3.13 wheels can be build and uploaded to PyPI.

Since Fiona is a low-level dependency for many downstream projects, it would be beneficial to have Python 3.13 on PyPI as fast as possible, ideally in the 1.10 release.

cibuildwheel 2.20 now uses the latest Python 3.13.0rc1 and build Python 3.13 by default (pypa/cibuildwheel#1950), which could help the process.

Edit: This is the issue to track

• Python 3.13 sgillies/fiona-wheels#46

Leaving this open since not everyone might know where the Fiona wheels get build

Done!
