Introduction
Split up documentation This breaks apart the massive "index" document into 1. An "index" document that explains how to install and set up fish and links to the other documents 2. A "fish-language" document that describes the syntax and semantics of the language 3. A "fish-interactive" document that describes how to use fish interactively No change to the content has been made, only the parts have been moved from index and some of the formatting (links and header levels) were fixed. See #7348.

A shell is a program that helps you operate your computer by starting other programs. fish offers a command-line interface focused on usability and interactive use.
docs: Streamline some of the introductory parts of index.rst Really "what is a shell" is covered by the part where it says it offers a commandline interface.

Where to go?
============
docs: Split off links to other pages into its own section This is an attempt to make these more visible - the intro section explains what this is, and then we mention where to go, and after that we go into installation and stuff. I don't think putting "where to go" *after* the installation instruction is correct, but maybe it is? For the time being, we keep the order as it is.

Because shell scripts are written in many different languages, they need to carry information about which interpreter should be used to execute them. For this, they are expected to have a first line, the shebang line, which names the interpreter executable.
