Rust: error: 'cargo-clippy' is not installed for the toolchain 'nightly-x86_64-apple-darwin' but is available on the path

[duckpuppy]

Describe the bug
When setting language.rust.enable = true, all the toolchain packages are available, including cargo-clippy. However, cargo does not seem to know it's there.

To reproduce
https://gist.github.com/duckpuppy/ac757f17ad717429860a79fe031d838b

$ cargo init
     Created binary (application) package

$ cargo clippy
error: 'cargo-clippy' is not installed for the toolchain 'nightly-x86_64-apple-darwin'
To install, run `rustup component add clippy`

$ cargo-clippy
    Checking test-rust-clippy v0.1.0 (/Users/paikens/src/personal/test-rust-clippy)

hey @duckpuppy can you try again with latest main now that #667 has landed?

if it still doesn't work, can you try again with languages.rust.channel = "stable";?

[duckpuppy]

Sorry for the late reply - this is still an issue after that merge, even using fenix (via setting the channel to "stable" and including the fenix input).

inputs:
  nixpkgs:
    url: github:NixOS/nixpkgs/nixpkgs-unstable
  fenix:
    url: github:nix-community/fenix
    inputs:
      nixpkgs:
        follows: nixpkgs

{ pkgs, ... }:

{
  packages = [ pkgs.git ];

  languages.rust.enable = true;
  languages.rust.channel = "stable";
}

EDIT: This was on a fresh devenv init. I verified that I was using the PR in question by not including the fenix input in devenv.yaml to get the error output about the missing fenix input when specifying the "stable" channel.
