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 :)
