Hi, I'm trying to install ckanext-dcat in my Dockerfile. However, while installing the requirements, rdflib-jsonld 0.4.0 failed to install:

v58.0.0 04 Sep 2021

Breaking Changes

2086: Removed support for 2to3 during builds. Projects should port to a unified codebase or pin to an older version of Setuptools using PEP 518 build-requires.

Workaround: downgrade setuptools to v57.5.0 before installing the requirements

RUN pip install --force-reinstall 'setuptools<58.0.0'

rdflib-json already dropped use_2to3 since v0.6.1, is it possible to upgrade rdflib-json to a newer version?

Should be fixed with https://github.com/ckan/ckanext-dcat/pull/213
