Christian Berendt f3756b0a37 [upstream-training] improve the index.rst file

* remove the "Indices and tables" slide

There is no need for a "Indices and tables" slide. The slide is
confusing and should be removed.

* convert the index.rst file from a default Sphinx documentation
  index.rst file into a more useful hieroglyph index.rst file
