[PATCH v2] Documentation: kunit: Fix "How Do I Use This" / "Next Steps" sections

[David Gow <davidgow@google.com>]

The "How Do I Use This" section of index.rst and "Next Steps" section of
start.rst were just copies of the table of contents, and therefore
weren't really useful either when looking a sphinx generated output
(which already had the TOC visible) or when reading the source (where
it's just a list of files that ls could give you).

Instead, provide a small number of concrete next steps, and a bit more
description about what the pages contain.

This also removes the broken reference to 'tips.rst', which was
previously removed.

Fixes: 4399c737a97d ("Documentation: kunit: Remove redundant 'tips.rst' page")

Thanks everyone for reviewing v1. Since this is pretty much a complete
rewrite, I've left Reviewed-by tags off, as I don't feel the previous
reviews totally apply. Feel free to review again if you have any
comments.

Cheers,
-- David

Changes since v1:
https://lore.kernel.org/linux-kselftest/20221129094732.306449-1-davidgow@google.com/
- Totally rewrite both sections to only include (and provide more
  context for) the most concrete next steps.
  - Thanks Bagas for pointing out that this basically duplicates the TOC
    as-is.
