Dear Maintainer,

after updating python-bleach to 5.0.0 your package from testing fails
together wich python3-bleach from unstable.

e.g. on amd64
https://ci.debian.net/data/autopkgtest/testing/amd64/n/nbconvert/23478280/log.gz

The error in detail looks like this:

autopkgtest [20:13:04]: test autodep8-python3: set -e ; for py in $(py3versions -r 2>/dev/null) ; do cd "$AUTOPKGTEST_TMP" ; echo "Testing with $py:" ; $py -c "import nbconvert; print(nbconvert)" ; done

It might be enough to add python3-packaging as new dependency?
