This allows us to organize the TOC a bit better by adding sections per
major version. We can even increase the maxdepth to 2 now, which looks
great in my opinion.

In addition, the full list of releases is not shown in the sidebar
anymore when viewing a completely different part of the documentation,
which took up more than half of the total sidebar entries.

With older versions of the RTD theme, paragraphs in nested lists would
lead to inconsistent spacing. This has been fixed, so we can remove our
workaround to use line blocks instead of paragraphs.

2 spaces is the most common indentation width used in the docs; adjust
the rest for consistency.

Also change .editorconfig accordingly.
