Tables instead of bullet point lists in documentation

[arialdomartini]

This is surely a personal preference, but I find tables more readable and convenient to reference than bullet point lists.

So instead of having list of operators and functions like this:

https://github.com/jj-vcs/jj/blob/master/docs/revsets.md#operators
https://github.com/jj-vcs/jj/blob/master/docs/revsets.md#functions

I find this layout more tidy and easy to consult:

https://github.com/arialdomartini/jj/blob/tables/docs/revsets.md#operators
https://github.com/arialdomartini/jj/blob/tables/docs/revsets.md#functions

When descriptions are too long, though (see function remote_bookmarks, for example), it could be nice to have a shorter description in the reference table, with a separate paragraph with further details. Reason why I refrained from applying tables to Built-in Aliases.

Finally, unfortunately Markdown does not support multi-line cell contents, so you might hate the resulting source code of this PR.

I think it wouldn't help in all the situations. Is it still readable in jj help -k revsets, with ~80 terminal width?

[arialdomartini]

Good question. I haven't checked.

I also don't like how the line in each table cell stretches so long.

Isn't this change going against the Google markdown styleguide regarding tables?

Avoid using tables when your data could easily be presented in a list.

Seems so. It should be closed then.
