Clippy Book Chapter Updates Reborn: Lint Passes
This PR adds a new chapter to the book: "Lint passes". No major changes apart from some re-phrasing, fixing typos... etc.
## Notes
- Requires #10595 to be merged before this one (Or else, a link will be broken).
- To talk about the whole project, please use the tracking issue for the project #10597 (It also contains a timeline, discussions and more information)
changelog: Add a new "Lint passes" chapter to the book
r? `@flip1995`
Links to README.md files must actually be links to index.md files,
because of the inner workings of `mdbook`.
Also use the latest mdbook version in CI.
Clippy Book Chapter Updates Reborn: Type Checking
This PR adds a new chapter to the book: "Type Checking", it hasn't changed a lot from the source mainly because there wasn't many reviews on it and I haven't see a lot of things that needed a change.
## Notes
- I have some doubts about the whole "`is_*` Usage" section, what do you think about it.
- For discussion about the whole project, please use the tracking issue for the project #10597 (It also contains a timeline, discussions, and more information)

Update subtree sync docs for changes in rustc-dev-guide
Companion PR to https://github.com/rust-lang/rustc-dev-guide/pull/1653. That still keeps a `contributing.html` with an "External Contributions" section, so hopefully it won't be too disruptive.
changelog: none
