`man beet` refers to a section that doesn't exist

The beets 'man' page is a great source of documentation. I noticed a small issue though. In the section for `beets ls` it says this:

```
Want to search for "Gronlandic Edit" by of Montreal? Try beet list gronlandic.
Maybe you want to see everything released in 2009 with "vegetables" in the
title? Try beet list year:2009 title:vegetables. You can also specify the sort
order. (Read more in query.)
```

The last sentence ("Read more in query") seems to refer the reader to a section that doesn't actually exist in the 'man' page.

In the online docs, [this section](https://beets.readthedocs.io/en/latest/reference/cli.html#list) comes out as: "(Read more in [Queries](https://beets.readthedocs.io/en/latest/reference/query.html).)".
