This removes the explicit html coloring that was used in the tutorial.
Where necessary we just add pseudo-html like `<red>...</red>` to
explain it to the users.
I don't know how to reintroduce coloring here, but it's not super
important as the user can always just check for themselves.
See #5696

We also might want to remove the mailing list and/or IRC channel as I
think most devs aren't on them anymore, but let's just add the channel
that I prefer first.

This displays a colored prompt, which we emulate by adding explicit
roles that are translated to css classes.
For other things, like "eror" this might not be enough because those
often need the rest of the line to still be styled, and I've not found
a way to add some explicit styling to a code block.
See #5696.

We were flip-flopping between the two terms, so we now use one. We
still mention "array" in the chapter, and it's still `read --array`,
though.
Fixes#5846.

fish_indent_lexer formats lines not starting with a prompt indicator
as output, as long as there is a prompt indicator elsewhere.
So these tags are useless and wrong.
See #5696.

There's an explicit label for "cartesian-product", but the title is
"Cartesian Product*s*". So linking via with `thing <#link>`_ links the
title, so without the "s" it doesn't work.
From what I know, linking via :ref:`thing <label>` is preferred and
works better with other exports and across files?
I think I should take a doc holiday.
