We may add setuptools<81 to requirements-dev.txt to suppress the deprecation warning. This pins setuptools to a version that doesn't emit the warning, as recommended in the warning message.

This may be temporary workaround until sphinxcontrib-redoc migrates from pkg_resources to importlib.metadata. Once that package is updated, we can remove this pin.

This issue aims to share this analisys and make us to not forget how to resolve it when the next version of sphinxcontrib-redoc will be available.
