This adds a wrapper for fish which allows creating shells pre-initialised with some completions, functions, and configuration scripts from given paths or from fish plugin packages (`pkgs.fishPlugins.*`). This is especially handy when one wants to try a plugin in an ephemeral shell. GitHub: see https://github.com/NixOS/nixpkgs/pull/107834#discussion_r550612519
