Configure Nix to use the Devbox cache as a substituter.
If the current Nix installation is multi-user, this command grants the Nix daemon access to Devbox
caches by making the following changes:
Adds the current user to Nix’s list of trusted users in the system nix.conf.
Adds the cache credentials to ~/.aws/config.
Configuration requires sudo, but only needs to happen once. The changes persist across Devbox
accounts and organizations.This command is a no-op for single-user Nix installs that aren’t running the Nix daemon.
