git-filter-repo fails to build with Python 3.13.0a2.

I don't know whether Python 3.13 is a culprit in this case, but the package builds successfully in Koschei, hence reporting to increase visibility.

This report is automated and not very verbose, but we'll try to get back here with details.

For the build logs, see:

For all our attempts to build git-filter-repo with Python 3.13, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.13/package/git-filter-repo/

Testing and mass rebuild of packages is happening in copr.
You can follow these instructions to test locally in mock if your package builds with Python 3.13:
https://copr.fedorainfracloud.org/coprs/g/python/python3.13/

Let us know here if you have any questions.

Python 3.13 is planned to be included in Fedora 41.
To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.13.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires),
so if this package is required a lot, it's important for us to get it fixed soon.

We'd appreciate help from the people who know this package best,
but if you don't want to work on this now, let us know so we can try to work around it on our side.
