Rollup merge of #29549 - brson:docidx, r=steveklabnik

I noticed the nomicon was not listed!

I also removed links to racer and rustfmt since they were not *doc-specific* links, just links to tools, as well as pointed the cargo link directly at the docs.

Removed all the community stuff. There are lots of other places to find this now, including the website.

With pending website changes this page will continue to be pared back, reflecting only what's in-tree, not general Rust docs.

-# Community & Getting Help
-
-If you need help with something, or just want to talk about Rust with others,
-there are a few places you can do that:
-
-The Rust IRC channels on [irc.mozilla.org](irc://irc.mozilla.org/) are the
-fastest way to get help.
-[`#rust`](http://chat.mibbit.com/?server=irc.mozilla.org&channel=%23rust) is
-the general discussion channel, and you'll find people willing to help you with
-any questions you may have.
-
-There are also three specialty channels:
-[`#rust-gamedev`](http://chat.mibbit.com/?server=irc.mozilla.org&channel=%23rust-gamedev)
-and
-[`#rust-osdev`](http://chat.mibbit.com/?server=irc.mozilla.org&channel=%23rust-osdev)
-are for game development and operating system development, respectively.
-There's also
-[`#rust-internals`](http://chat.mibbit.com/?server=irc.mozilla.org&channel=%23rust-internals), which is for discussion of the development of Rust itself.
-
-You can also get help on [Stack
-Overflow](https://stackoverflow.com/questions/tagged/rust). Searching for your
-problem might reveal someone who has asked it before!
-
-There is an active [subreddit](https://reddit.com/r/rust) with lots of
-discussion and news about Rust.
-
-There is also a [user forum](https://users.rust-lang.org), for all
-user-oriented discussion, and a [developer
