[docs] [issue33187] Document ElementInclude (XInclude) support in ElementTree

[Stefan Behnel]

New submission from Stefan Behnel <stefan_ml at behnel.de>:

The ElementInclude module in ElementTree seems undocumented. I couldn't find any documentation in the stdlib docs. Pretty much the only source that I could find is here:

http://effbot.org/zone/element-xinclude.htm

I noticed it while looking for a place to document the changes of #20928.
