ci: run checks-py3 using v2.0 images The changes in test-check-sdist.t are related to the "egg-info" directory inside the tarball. Apparently the newer versions of whatever `setup.py sdist` is using now adds this directory with various meta information about the package, so now we have 5 more files in the tarball. The exact files are: hg_evolve.egg-info/ hg_evolve.egg-info/PKG-INFO hg_evolve.egg-info/SOURCES.txt hg_evolve.egg-info/dependency_links.txt hg_evolve.egg-info/top_level.txt
