DOC: remove long listings in the tutorials.rst page
State: closed

Triggered by discussion in https://github.com/pandas-dev/pandas/pull/24117: currently some of the listed tutorials have a very long included table of content, others much less. Here I kept the current list of tutorials, but simply removed detailed tocs of all of them. Each of them can do that on the page you land on when clicking on the single link.
