nvim: Exchange headlines plugin for markdown.nvim

To render markdown highlights and a few other things (list items, code
blocks, callouts, etc) we switched from headlines.nvim to markdown.nvim
(internally ralled render-markdown).
This now also enables quick switching between showing the rendered
output and raw markdown (`<leader>pp`).
