Add typos + cargo doc CI (#32)

* ci: add separate `typo` job

* add `typos.toml` for false positives

* fix all typos

* ci: add `cargo doc` step

* fix doc errors

* contributing.md: update passing CI steps

* fix more typos, add exception to `cryptonight/`

* ci: move `cargo doc` step within `ci` job

It needs dependencies.

* ci: add https://github.com/Cuprate/cuprate/pull/63

* test-utils: fix typo

* ci: switch `rustup update` and switch order

* ci: only update rust on unix

* ci: set `RUSTDOCFLAGS` env earlier

* ci: only run `cargo doc` on linux

* ci: remove `bash` on `cargo doc`

* ci: remove `--all-targets`

We now have the target OS's in CI, no need to compile for each.

* contributing.md: update ci steps

* ci: add `--all-targets` back to clippy, build

* update contributing.md

 ## Passing CI
+The first 3 steps to CI are formatting, typo, and documentation checking.
 
-To pass CI make sure all these successfully run:
+Check if your changes are formatted, typo-free, and documented correctly by running:
+- `cargo fmt --all --check`
+- `typos`
+- `RUSTDOCFLAGS='-D warnings' cargo doc --workspace --all-features`
 
-- `cargo clippy --workspace --all-targets --all-features -- -D warnings`
+`typos` can be installed with `cargo` from: https://github.com/crate-ci/typos.
+
+After that, ensure all lints, tests, and builds are successful by running:
+
+- `cargo clippy --workspace --all-features --all-targets -- -D warnings`
 - `cargo fmt --all`
-- `cargo test`
+- `cargo test --all-features --workspace`
-- `cargo build`
+- `cargo build --all-features --all-targets --workspace`
