feat(telescope): add nvchad borderless telescope style

[AlejandroSuero]

@scottmckendry I think it would be a good thing to allow for a separation style borderless telescope, like NvChad "borderless", but allowing for this to be opt-out like catppuccin does in their integrations section.

Note

I made it so the changes are compatible with the current way of configuring the colorscheme.

In the video the options are { ..., theme = "nvchad" } but I changed after recording it to style

It can be change to be a BREAKING CHANGE and have it like:

require("cyberdream").setup({
  -- ...
  telescope = {
    borderless = true,
    style = "nvchad",
  },
  -- ...
})

The good thing about adding this PR (in my opinion) is that it leads to having styles like "nvchad_inversed", and do one that it will keep the base borderless` but light up the results section for example.

@scottmckendry for the blueish theme, I used this in my nvim-config:

require("cyberdream").setup({
  theme = {
    overrides = function(colors)
      TelescopePromptPrefix = { fg = colors.blue },
      TelescopeMatching = { fg = colors.cyan },
      TelescopeResultsTitle = { fg = colors.blue },
      TelescopePromptCounter = { fg = colors.cyan },
      TelescopePromptTitle = { fg = colors.bg, bg = colors.blue, bold = true },
    end,
  },
})

And here is how it looks in action:

This is a very clever implementation! Great work, yet again @AlejandroSuero!

I've added another style to represent the default value. It makes it more obvious that there's a difference between nvchad and the old default styling. It will be cool having multiple styles to choose from in future 🚀
