1.1: test suite uses no longer maintained pytest-expect

[kloczek]

html5lib test suite uses pytest-expect which seems is not maintained since 2016.
pytest-expect additionally used in its own test suite umsgpack which is already marked as deprecated gsnedders/pytest-expect#15.
On refreshing html5lib for python 3.10 and 3.11 looks like it would be good to remove or replace those bits as well.

Is there anything specific that doesn't work for you?

Yes. It is not possible to package that module using pep517.

Gentle ping .. any update? 🤔

sphinx still needs html5lib and pytest-expect cannot be used as well with last 8.x pytest.
To be hones now sphinx is on the way to drop html5lib however few other modules still needs html5lib 😞
