[issue40065] py39: remove deprecation note for xml.etree.cElementTree

[Fred Drake]

Fred Drake <fdrake at gmail.com> added the comment:

The Python 2.7 documentation was not clear that xml.etree.cElementTree was optional, so users who didn't dive into the implementation or build process could easily not have known unless someone with a more limited installation used their code.
