Fix prettier

[DockterTeagle]

This is a heavy handed approach and is very ... naive, it just removes all mentions of prettier-toml.

oh shit this has one more commit than i thought it did, whoops. Imma have to drop the more recent commit.

the interface will change upstream: NixOS/nixpkgs#442943

 pkgs.prettier.override {
   plugins = with pkgs.prettier.plugins; [
     prettier-plugin-php
     prettier-plugin-pug
     prettier-plugin-ruby
     prettier-plugin-xml
     # ...
   ];
 }

much more convenient

I think this might depend on the referential flakes being resolved, as we can't use that nixpkgs until we can up our nix for CI(?).
