live_grep doesn't work with ripgrep from nixpkgs on PATH, but works with ripgrep from homebrew on PATH (nushell)

Description

On my macbook, using nix-darwin and nushell, the version of ripgrep from nixpkgs does not work with live_grep - I get this error:

[telescope.live_grep]: 'ripgrep', or similar alternative, is a required dependency for the live_grep picker. Visit https://github.com/BurntSushi/ripgrep#installation for installation instructions.

I've verified that rg is on my PATH:

~ 
❯ which -a rg | to text
command: rg
path: 
type: external
command: rg
path: /Users/rykugur/.nix-profile/bin/rg
type: external

However, if I install it via homebrew and add /opt/homebrew/bin to my path (and thus have two instances of rg on my PATH), live_grep works fine.

Additionally, on my linux desktop (running nixOS with the same nushell config), the version of ripgrep from nixpkgs works fine for live_grep.

My telescope config for neovim is mostly the standard config from LazyVim extras.

NOTE: fd is also on my path, even though the checkhealth command says otherwise.

Neovim version

NVIM v0.10.2
Build type: Release
LuaJIT 2.1.1713773202
