Add support for nvim-tree.lua

[jiyometrik]

i noticed that the melange colors are weird in nvim tree when it is loaded in init.lua using

vim.cmd('colorscheme melange')

loaded in init.lua

loaded after init using :colorscheme melange

can this be solved?

Reading the nvim-tree.lua docs:

Syntax highlighting uses g:terminal_color_ from colorschemes, fallbacks to ugly colors otherwise.

So the problem is likely that melange doesn't set these variables explicitly.
