nixpkgs-vet: update CI, docs, and release to 0.1.4

Browse Source 
Everything gets moved into the `ci/` top-level directory.

We keep behind `maintainers/scripts/check-by-name.sh` and `pkgs/test/check-by-name/pinned-version.txt` as they are going to cause CI errors and confusion until we get all the way through the various channels.
They'll be removed in about a week or so.

[`pinned-nixpkgs.json`](./pinned-nixpkgs.json) contains a pinned Nixpkgs version tested by Hydra.
Run [`update-pinned-nixpkgs.sh`](./update-pinned-nixpkgs.sh) to update it.
## `ci/nixpkgs-vet.sh BASE_BRANCH [REPOSITORY]`
Runs the [`nixpkgs-vet` tool](https://github.com/NixOS/nixpkgs-vet) on the HEAD commit, closely matching what CI does. This can't do exactly the same as CI, because CI needs to rely on GitHub's server-side Git history to compute the mergeability of PRs before the check can be started.
In turn, when contributors are running this tool locally, we don't want to have to push commits to test them, and we can also rely on the local Git history to do the mergeability check.
Arguments:
- `BASE_BRANCH`: The base branch to use, e.g. master or release-24.05
- `REPOSITORY`: The repository from which to fetch the base branch. Defaults to <https://github.com/NixOS/nixpkgs.git>.
## `ci/nixpkgs-vet`
This directory contains scripts and files used and related to [`nixpkgs-vet`](https://github.com/NixOS/nixpkgs-vet/), which the CI uses to implement `pkgs/by-name` checks, along with many other Nixpkgs architecture rules.
See also the [CI GitHub Action](../.github/workflows/nixpkgs-vet.yml).
## `ci/nixpkgs-vet/update-pinned-tool.sh`
Updates the pinned [`nixpkgs-vet` tool](https://github.com/NixOS/nixpkgs-vet) in [`ci/nixpkgs-vet/pinned-version.txt`](./nixpkgs-vet/pinned-version.txt) to the latest [release](https://github.com/NixOS/nixpkgs-vet/releases).
Each release contains a pre-built `x86_64-linux` version of the tool which is used by CI.
This script currently needs to be called manually when the CI tooling needs to be updated.
Why not just build the tooling right from the PRs Nixpkgs version?
- Because it allows CI to check all PRs, even if they would break the CI tooling.
- Because it makes the CI check very fast, since no Nix builds need to be done, even for mass rebuilds.
- Because it improves security, since we don't have to build potentially untrusted code from PRs.
The tool only needs a very minimal Nix evaluation at runtime, which can work with [readonly-mode](https://nixos.org/manual/nix/stable/command-ref/opt-common.html#opt-readonly-mode) and [restrict-eval](https://nixos.org/manual/nix/stable/command-ref/conf-file.html#conf-restrict-eval).
