Subject: [PATCH] feat!: replace todo-comments.nvim Highlightning is done via
 mini.hipatterns so the only reason to keep todo-comments was `:TodoQuickFix`.
 As a replacement I wrote a very light-weight and basic function. Of course,
 the plugin is more sophisticated but for my use-case I hope that my custom
 solution is enough :)
