Rollup merge of #107062 - tgross35:update-doc-index, r=ehuss

Do some cleanup of doc/index.md

I think a lot of people get to this landing page from `rustup doc`, and it's a bit tricky to find some useful information. I attempted to clean it up here a bit, from the commit message:

- Add quick link to API docs
- Add marker for external links, to help offline users
- Add information about using 'cargo doc' and the playground
- Clean up some of the wording
- Update body & header style to match rustdoc defaults
- Bump heading levels so main page header is 1, others are 2 (all were level 1 before)

Welcome to an overview of the documentation provided by the [Rust
project]. This page contains links to various helpful references,
most of which are available offline (if opened with `rustup doc`). Many of these
resources take the form of "books"; we collectively call these "The Rust
Bookshelf." Some are large, some are small.

## Learning Rust
If you'd like to learn Rust, this is the section for you! All of these resources
assume that you have programmed before, but not in any specific language:
## The Rust Programming Language
### The Rust Programming Language
Affectionately nicknamed "the book," [The Rust Programming
Language](book/index.html) will give you an overview of the language from
first principles. You'll build a few projects along the way, and by the end,
you'll have a solid grasp of the language.

## Rust By Example
### Rust By Example
If reading multiple hundreds of pages about a language isn't your style, then
[Rust By Example](rust-by-example/index.html) has you covered. While the book talks about code with
a lot of words, RBE shows off a bunch of code, and keeps the talking to a
minimum. It also includes exercises!

## Rustlings
### Rustlings
[Rustlings](https://github.com/rust-lang/rustlings) guides you through downloading and setting up the Rust toolchain,
and teaches you the basics of reading and writing Rust syntax. It's an
alternative to Rust by Example that works with your own environment.
[Rustlings](https://github.com/rust-lang/rustlings) guides you

# Use Rust
### Rust Playground
Once you've gotten familiar with the language, these resources can help you
when you're actually using it day-to-day.
The [Rust Playground](https://play.rust-lang.org) is a great place
to try out and share small bits of code, or experiment with some of the most
popular crates.
## The Standard Library
Rust's standard library has [extensive API documentation](std/index.html),
with explanations of how to use various things, as well as example code for
accomplishing various tasks.

## The Edition Guide
### Your Personal Documentation
[The Edition Guide](edition-guide/index.html) describes the Rust editions.
Whenever you are working in a crate, `cargo doc --open` will generate
documentation for your project _and_ all its dependencies in their correct
version, and open it in your browser. Add the flag `--document-private-items` to
also show items not marked `pub`.
## The Rustc Book
### The Edition Guide
[The Rustc Book](rustc/index.html) describes the Rust compiler, `rustc`.
[The Edition Guide](edition-guide/index.html) describes the Rust editions and
their differences.
## The Cargo Book
### The `rustc` Book
[The Cargo Book](cargo/index.html) is a guide to Cargo, Rust's build tool and dependency manager.
[The `rustc` Book](rustc/index.html) describes the Rust compiler, `rustc`.

[The Rustdoc Book](rustdoc/index.html) describes our documentation tool, `rustdoc`.
## The Clippy Book
### The Clippy Book
[The Clippy Book](clippy/index.html) describes our static analyzer, Clippy.
## Extended Error Listing
### Extended Error Listing
Many of Rust's errors come with error codes, and you can request extended
diagnostics from the compiler on those errors. You can also [read them
here](error_codes/index.html), if you prefer to read them that way.

### The Reference
[The Reference](reference/index.html) is not a formal spec, but is more detailed and

## The Style Guide
### The Style Guide
[The Rust Style Guide](style-guide/index.html) describes the standard formatting of Rust
code. Most developers use rustfmt to format their code, and rustfmt's default
formatting matches this style guide.

[The Rustonomicon](nomicon/index.html) is your guidebook to the dark arts of unsafe
Rust. It's also sometimes called "the 'nomicon."
