DOC: Discussion on new getting started page (Numfocus Grant)
As currently prepared together with @jorisvandenbossche, the following document is a proposal on how to adjust the getting started page and section of the documentation: https://docs.google.com/document/d/1Rc_eql5KLrdf0c582KyWfs2ADVNxbJy4jfosnqdrVak/edit?usp=sharing

The general idea is to split the current 10 minutes into 10 x 1' topics of Pandas. Input is very welcome on:
- the topics to pick and how to introduce them
- the content of the introduction tutorial linked to each of the topics
