How to enable Fortran file icons in nvim-tree?

[EhsanAramide]

I tested *.f, *.f90 and *.for but none of them work.

Icons are provided by https://github.com/nvim-tree/nvim-web-devicons/. Can't remember if Fortran icon is there, but it's easy to add if it's missing.

I opened an issue. Actually, the wrong file extension has been set.
