Rather than having a misc tutorial page in the grab-bag "package management" section, this information should just be part of the S3 store docs.

this is the first thing most beginners see, and it misleads them into
assuming `nix-env` is appropriate for doing anything but setting and
reverting profile generations.
this chapter is the root of most evil around the ecosystem, and today we
finally close it for good.
this is a how-to guide which should not be in the reference manual.
it also refers to `nix-env`, which should not be the first thing readers
of the reference manual encounter, as it behaves very differently in
spirit from the rest of Nix.
slightly reword the documentation to be more concise and informative.
e.g. nix-env -e subversion => nix-env --uninstall subversion
The aim is to make the documentation less cryptic for newcomers and the
long options are more self-documenting.
The change was made with the following script:
<https://github.com/aschmolck/convert-short-nix-opts-to-long-ones>
and sanity checked visually.
it is out of date, all over the place in level of detail, is really
about `nixpkgs`, and in general instructions should not be part of
a reference manual.
also:
- update redirects and internal links
- use "Nix language" consistently
They are equivalent according to
<https://spec.commonmark.org/0.29/#hard-line-breaks>,
and the trailing spaces tend to be a pain (because the make git
complain, editors tend to want to remove them − the `.editorconfig`
actually specifies that − etc..).
