Allow update to autodocs-type-hints 2.3.0, and Sphinx 7.4.x when running with Python 3.9+. The patch is primarily for the debian packaging team to package RDFLib 7.1.2 with Sphinx 7.4 and autodocs-type-hints v2.3, on Python 3.9+.
enable Sphinx autodoc preservation of method-argument defaults . This avoids build-time variation such as object memory addresses from inadvertently leaking into the packaged documentation.
