RST lists could use some spacing between items

[tbrlpld]

Markdown lists use paragraphs for the content. That creates some spacing between the list items. The is another topic that we also need to address because it seems to create to much spacing.

What I am concerned with there is the list that are generated from RST input. There Sphinx does not seem to use the same approach leading to very dense lists. The denseness is an issue when the content is longer paragraphs as can be expected in step-by-step guides.

E.g. this:

https://wagtail--6930.org.readthedocs.build/en/6930/editor_manual/finding_your_way_around/the_dashboard.html

I find it very hard to read. I think we should add some spacing between the list items that is larger than the line height.

This one is complicated. The root of this is actually these lines

li > p {
  margin-bottom: 0;
}

present in custom.css as a workaround for executablebooks/MyST-Parser#533.
