[Ben Beasley]

Things to check first

• I have searched the existing issues and didn't find my bug already reported there

• I have checked that my bug is still present in the latest release

Typeguard version

Python version

What happened?

There were a huge number of test errors because filterwarnings = ["error"] is set in pyproject.toml and there is a new DeprecationWarning in Python 3.13.
