[issue38022] IDLE: Upgrade help.html to sphinx 2

[Tal Einat]

New submission from Tal Einat <taleinat at gmail.com>:

The rest of our docs use version 2.x of Sphinx with its new HTML5 output writer.  However, IDLE's help.html is a version of idle.rst rendered with the old writer, via the `-D html4_writer=1` command line parameter.

The reason for this is that the new output is slightly different, and causes some regression in how IDLE's HTML help renderer displays the help information.

I propose to upgrade the IDLE HTML help renderer to properly handle the new output.
