Add 3.11-dev as TODO item says

Refs #11662

Looks like some C-API has changed: #include "longintrepr.h", lxml does not compile on 3.11-dev

[sobolevn]

I am going to apt-get install libxml2 libxslt to see if that works.

Quoting the changelog for 3.11: https://github.com/python/cpython/blob/cf7eaa4617295747ee5646c4e2b7e7a16d7c64ab/Doc/whatsnew/3.11.rst

The non-limited API files cellobject.h, classobject.h, context.h, funcobject.h, genobject.h and longintrepr.h have been moved to the Include/cpython directory. Moreover, the eval.h header file was removed. These files must not be included directly, as they are already included in Python.h

I've just ignored lxml for python 3.11 yet. So, here are the failing tests:
