[issue21971] Index and update turtledemo doc.

[Terry J. Reedy]

New submission from Terry J. Reedy:

The doc section for the turtledemo package do not appear in either the module index or the general index. It should appear in both.
https://docs.python.org/2.7/library/turtle.html#demo-scripts
https://docs.python.org/3.4/library/turtle.html#demo-scripts

This comment about the two-canvases demo, "Therefore it only can be run standalone." was previously obsolete is that it could be run from the demo viewer, but the text did not load. After the fix for #21882, the text load and it works find in the viewer. It should be added to the table and the count adjusted.
