Makes overrideAttrs usable in the same way that `override` can be used.
It allows the first argument of `overrideAttrs` to be either a function
or an attrset, instead of only a function:
hello.overrideAttrs (old: { postBuild = "echo hello"; })
hello.overrideAttrs { postBuild = "echo hello"; }
Previously only the first example was possible.

This is actually relatively complicated to achieve, since it involves
overriding GHC on e.g. aarch64-darwin, so the FAQ entry seems warranted.
It's also a good exercise to me, since it demonstrates some problems
with the overriding infrastructure, i.e. that it has a tendency to
inherit the pkgs fixpoint from prev. An example of this problem is
https://github.com/NixOS/nixpkgs/issues/235960, but it has different
manifestations as well. Awareness of this will also help writing the
other sections on overriding.
How complicated it is, seems to be further incentive to go ahead with
https://github.com/NixOS/nixpkgs/pull/239548 as well.
This reverts commit 7e6c518ce4.
I misinterpreted Github's CI failure in the notification tab and
thought that I had broken CI on origin/master, so I panic-reverted
before I merged it (I thought they had).
On closer inspection, it appears that the CI failure was not from
the tip that I merged. This PR resubmits the reverted change. I'll
wait for OfBorg to finish this time.
The manual does an okay job of explaining the rules for each of the
three development branches, but really doesn't give any intuition as
to why there are three (why not four? or two?) or how we got where
we are today.
This commit attempts to fix that, by explaining that there is one
branch that allows mass-rebuild commits, and it has a fast-building
branch both upstream and downstream of it (from the perspective of
automated merges).
I have also removed the term "stabilization" from the arc labels.
This vague term is not defined anywhere, and does communicate any
useful information without a longer explanation. Therefore it is
not appropriate for use in a diagram.

It may have to be fetchpatch, fetchpatch2, or fetchurl. We should link somewhere, but we don't have a link target yet, so until then, remove the inaccurate info.

nixos-render-docs does not support this, and since the examples are
small there isn't that much value in callouts here. change them to
simple MD code blocks and lists instead.
pandoc recognizes `::: note` admonitions, nixos-render-docs only
recognizes `::: {.note}`. surprisingly pandoc also emits the correct
docbook tags for `[](#xref)`s, so we can use that too.
skipping heading levels (eg from # to ###, or starting at ###) is legal
in pandoc, but not in nixos-render-docs. pandoc acts as though section
levels *were* consecutive, nixos-render-docs prefers to tell people not
to do that kind of thing because it can make documents more fragile.
