Auto merge of #79576 - m-ou-se:2021, r=Mark-Simulacrum
Add edition 2021.

:fireworks: Happy new ~~year~~ Rust. :champagne:

This adds --edition=2021, and updates suggestions about 2018 to say "2018 *or later*".

Related Cargo PR: https://github.com/rust-lang/cargo/pull/8922

---

Edit: This adds the new edition as *unstable*. Without `-Z unstable-options`, `--edition=2021` results in:
```
$ rustc --edition=2021
error: edition 2021 is unstable and only available with -Z unstable-options.
