Devbox is failing when an empty /nix folder exists

[ascknx]

What happened?

I want to use devbox in docker and mount the /nix volume.
Initially the volume is empty and I would expect that devbox can handle that.
But it fails with:
Error: We found a /nix directory but nix binary is not in your PATH and we were not able to find it in the usual locations. Your nix installation might be broken. If restarting your terminal or reinstalling nix doesn't work, please create an issue at https://github.com/jetify-com/devbox/issues

Steps to reproduce

1. create an empty /nix folder
2. start devbox
