trivial-builders: Deduplicate docs
I didn't have the opportunity to do all work at once, so I've added TODOs to bring attention to the situation.

## `fetchtorrent` {#fetchtorrent}
|

|

`fetchtorrent` expects two arguments. `url` which can either be a Magnet URI (Magnet Link) such as `magnet:?xt=urn:btih:dd8255ecdc7ca55fb0bbf81323d87062db1f6d1c` or an HTTP URL pointing to a `.torrent` file. It can also take a `config` argument which will craft a `settings.json` configuration file and give it to `transmission`, the underlying program that is performing the fetch. The available config options for `transmission` can be found [here](https://github.com/transmission/transmission/blob/main/docs/Editing-Configuration-Files.md#options)

The result of `runCommand name drvAttrs buildCommand` is a derivation that is built by running the specified shell commands.

Run the shell command `buildCommand` to produce a store path named `name`.

The attributes in `env` are added to the environment prior to running the command.

Environment variables set by `stdenv.mkDerivation` take precedence.

By default `runCommand` runs in a stdenv with no compiler environment.

`runCommandCC` uses the default stdenv, `pkgs.stdenv`.

Example:

```nix

runCommand "name" {envVariable = true;} ''echo hello > $out'';

```
|

The `*Local` variants force a derivation to be built locally,

it is not substituted.

This is intended for very cheap commands (<1s execution time).
|

It saves on the network roundrip and can speed up a build.

It is the same as adding the special fields
