Test failure on Python 3.13 because it strips indents from docstrings #1937
Description
Expected behavior and actual behavior.
In Python 3.13 (currently in alpha), as described in https://docs.python.org/3.13/whatsnew/3.13.html, “Compiler now strip indents from docstrings.” See python/cpython#81283.
There doesn’t yet seem to be a working Python 3.13 wheel for numpy on PyPI, which makes this awkward to reproduce in a virtualenv, but we are already doing early Python 3.13 testing in Fedora Linux.
As reported in https://bugzilla.redhat.com/show_bug.cgi?id=2250678, some tests fail due to the new docstring handling.

We expect that all tests should pass.
Steps to reproduce the problem.
Compile Shapely and run the tests on Python 3.13. (The hard part is getting a proper installation of Numpy.)
Operating system
Fedora Linux Rawhide – early testing of Python 3.13.
Shapely version and provenance
2.0.2, python-shapey
I intend to work on a PR for this.
