Yuan, any comments?

My only comment is that we should decide in which fontification
level(s) should the additional fontifications be.

The tests should be in python-tests.el, and should be skipped if
(treesit-ready-p 'python t) returns nil.

What problems with CI did you see?  I don't think I understand your
last sentence above.
