[FEATURE] Neovim Lua - Changing colors of neo-tree

[Curs3W4ll]

Is your feature request related to a problem? Please describe.
In the neo-tree window, there are colors that show the git states of the files (see screenshot below).

Describe the solution you'd like
It would be cool to be able to change these colors so it is more aesthetic (or make it use the same as git-signs).

Describe alternatives you've considered
Keep the old ugly colors.
