Input follows non-existant input

[traxys]

I have a flake that has this overlay as an input, and when used in other flake I get theinput <flake>/neovim-overlay/neovim-flake/nixpkgs follows a non-existent input "neovim-overlay/nikpkgs"

I believe this is a known bug with flakes, could it be considered to remove the follows directive, or will it be prolematic ?

If we remove follows, then we'll use the pinned nixpkgs revision from the neovim contrib flake (in the neovim git repo), which means it will rarely get updated.
