Title: nix-env --list-generations: List Profile Generations
Summary
The `nix-env --list-generations` command displays all existing generations for the active Nix profile. For each generation, it shows the creation date and highlights which one is currently active. Users can then switch to any of these listed generations using the `--switch-generation` operation. An example output demonstrates a list of generation numbers, their timestamps, and the '(current)' tag for the active generation.
