Update material-nf icons

The `nf-mdi-*` icons have been deprecated as of `v2.3.x`.
This commit exchanges them for their `nf-md` counterparts.

From https://github.com/ryanoasis/nerd-fonts/releases/tag/v2.3.3:

> The `v2.3.x` release has both, the 'old' and the 'new' codepoints to
> enable you an easier transition. Please change already now your
> prompts and other uses to the new codepoints. Release `v3.0.0` will
> finally drop the old codepoints (`F500` - `FD46`).
