print maintainers list

[GaetanLepage]

Description

This patch scraps the maintainers list from the package's metadata and displays it.

Motivation

When making a PR for updating a package, one has to tag the maintainers. Thus, I always find myself manually opening the source file of the package I update just to check the names of the maintainers.
Furthermore, their github handles are not always the same as their name and sometimes have to be looked up for in maintainers/maintainer-list.nix.

Preview

...
  maintainers = pkg.meta.maintainers or null;
  changelog = pkg.meta.changelog or null;
} --extra-experimental-features flakes nix-command
fetch https://github.com/astral-sh/ruff-lsp/releases.atom
Not updating version, already 0.0.50
Package maintainers:
  - figsoda (@figsoda)
  - Konstantin Alekseev (@kalekseev)
$ git -C /home/gaetan/perso/nix/nixpkgs diff -- /home/gaetan/perso/nix/nixpkgs/pkgs/development/tools/language-servers/ruff-lsp/default.nix

EDIT: In the terminal (mine at least), it appears in white, whereas the rest of the text is green, which makes it nicely visible.
