Rename `default.nix` to `<project>.nix`

[sgraf812]

As I'm trying to make sense of Nix, I was slightly confused that I couldn't just nix-build the default.nix. https://nixos.org/nixpkgs/manual/#users-guide-to-the-haskell-infrastructure suggests another approach, where the generated nix expression is instead saved as <project>.nix and then called from default.nix and probably release*.nix by extension.

Yeah, I'd accept a pull request to organize it that way

In this scenario would default.nix and release*.nix be the same thing?

Depends on whether you want to pin to some nixpks commit, so generally no. https://nixos.org/nixpkgs/manual/#how-to-create-nix-builds-for-your-own-private-haskell-packages gives examples for the most basic shell.nix and default.nix files. release*.nix is just a variant of default.nix that pins dependencies to be reproducible.
