Hi!

While rebuilding the python related packages against the Python 3.15rc1
version we found that sphinx-autodoc-typehints fails to build from
source [1].

The issue was already fixed and applied upstream [2].

I applied the upstream fix in the sandbox [3] to be able to build the
packages that depend on sphinx-autodoc-typehints, please consider
applying the patch to support the upcoming 3.15 version.

Happy hacking,
