This replicates behaviour found in the Nix2 commands, where IN_NIX_SHELL is set. This is for shells to determine whether they are inside of a Nix3 shell, and set a custom prompt accordingly. For example, Fish's Tide prompt framework checks for that environment variable and displays it in the prompt, indicating that the shell is in a Nix environment. This is not new behaviour, and the old Nix2 commands set the variable. If the shell that is created is a "pure" shell, ie --ignore-environment is passed, then IN_NIX_SHELL will be set to "pure". However, "nix develop" will always create an impure environment.
