feat: make picker window winhighlight option configurable

[nicholasxjy]

Add a winhighlight option for picker window, so we can style window a bit. like:

picker = {
  winhighlight = "Normal:DartPickNormal,FloatBorder:DartPickBorder"
}
-- some demo colors
vim.api.nvim_set_hl(0, "DartPickNormal", { fg = "cyan", bg = "#1a1926" })
vim.api.nvim_set_hl(0, "DartPickBorder", { fg = "red", bg = "#1a1926" })

Hi, and thanks for the PR!

I can appreciate the use case here, but I'd like to implement this slightly differently to avoid config option bloat. Namely, I'd like to simply return the win object from the Dart.pick() function so you could script the above like this:

local win = Dart.pick()
vim.api.nvim_set_option_value('winhighlight', 'Whatever:YouWant', { win = win })

This opens the door for your use case, but also many other possible use-cases - generally, it makes the picker window far more scriptable.

look great, yeah we better keep config clean and simple.

Added, you can see the readme for usage but it's basically what we've outlined here.
