wordpress: Add wordpressPackages

[onny]

Description of changes

This is the continuation of #124383 (thanks to @mohe2015 ) for packaging Wordpress plugins and themes. Similar to nodePackages, this approach uses a script (wp4nix) to generate Nix expressions using a list of package or theme names in json files.

So the workflow would be:

1. Add the package name to the wordpress-plugins.json file

[
  "add-widget-after-content"
, "antispam-bee"
, "async-javascript"
[...]

2. Run ./generate.sh
3. For example, use the package pkgs.wordpressPackages.plugins.antispam-bee in the Wordpress module like this:

services.wordpress = {
  sites."blog.${config.networking.domain}" = {
    plugins = with pkgs.wordpressPackages.plugins; [
      anti-spam-bee
      code-syntax-block
      lightbox-with-photoswipe
      wp-gdpr-compliance
    ];
    themes = [ pkgs.wordpressPackages.themes.geist ];
  };
}; 

This is also described in the README.md.

fixed

Strange if I run wp4nix from nixpkgs I get following error

When building wp4nix locally it works fine :(

@mohe2015 Unfortunately I couldn't manage to generate wordpressPackage sets using the json files generated by wp4nix, still trying to fix this but this is more difficult. Are you familiar with it?

Nothing came to my eye when looking at this PR but I'm not actively using NixOS any more so I can't check.

@dasJ @ajs124 @SlothOfAnarchy Thank you for your work on wp4nix. I would like to integrate Wordpress packaging into NixOS using the approach in this PR.

I would like to use the generated plugins, themes and language packages using your upstream Nix expression https://github.com/NixOS/nixpkgs/pull/173622/files#diff-e90349d673d80a4089a94ec946a314282f197cb3d431436a633ecd203fab0c8a

services.wordpress.sites."localhost" = {
  virtualHost.adminAddr = "hello@example.org";
  plugins = [ pkgs.wordpressPackages.plugins.wp-statistics ];
};

Unfortunately it currently fails

error: value is a function while a set was expected

Do you remember what was the right way to get this integrated?

Thanks to your work @mohe2015 I was able to get it to work :)
