Documentation for floating window border colors

[joe23rep]

Im creating a new colorscheme right now and would like to add specific colors for nvimtree.

Set up everything i wanted so far but i cant find out what highlight group you use for the floating window border.

Would be nice if you could add that to the documentation

nvim-tree doesn't actually do any styling of the floating window; it's just regular vim styling.

Take a look at base16-vim for inspiration.
