lapce: add module

[timon-schelling]

Description

Adds the 'programs.lapce' module for configuring lapce text editor.
Options for settings, plugins and keymaps are available. Idea #4541

Using the module would look something like this:

...
programs.lapce = {
  enable = true;
  package = pkgs.lapce;
  settings = {
    core = {
      custom-titlebar = false;
      color-theme = "Custom";
      icon-theme = "Material Icons";
    };
    editor = {
      font-family = "FiraCode Nerd Bold Font, monospace";
      font-size = 22;
      tab-width = 2;
      cursor-surrounding-lines = 4;
      render-whitespace = "all";
      bracket-pair-colorization = true;
      highlight-matching-brackets = true;
    };
    ui = {
      font-size = 20;
      open-editors-visible = false;
    };
    nushell-lsp = {
      path = "${pkgs.nushell}/bin/nu";
      args = [ "--lsp" ];
    };
    lapce-nix.lsp-path = "${pkgs.nil}/bin/nil";
  };
  plugins = [
    {
      author = "timon-schelling";
      name = "nushell-lsp";
      version = "0.1.0-rc2";
      hash = "sha256-/s982zGl85kxRoibwSpRiXxXD1Dgq6OUVvMXIUPP//4=";
    }
    {
      author = "MrFoxPro";
      name = "lapce-nix";
      version = "0.0.1";
      hash = "sha256-n+j8p6sB/Bxdp0iY6Gty9Zkpv9Rg34HjKsT1gUuGDzQ=";
    }
  ];
  keymaps = [
    {
      command = "open_log_file";
      key = "Ctrl+Shift+L";
    }
  ];
};
...

I'am allready using this in my nixos config via my fork. See this location.

I'm still interested in getting this into home manager. But before I rebase etc. I would like to know what other people think about my approach.
