🚨 Check building for docs.rs

[weiji14]

Ensure that documentation build will work for docs.rs at release time. Uses cargo-docs-rs running on Rust nightly.

Alternatively, run the following command locally:

cargo +nightly doc --all-features --config 'build.rustdocflags=["--cfg", "docsrs"]'
# or
cargo +nightly doc --all-features --config 'build.rustdocflags=["--cfg", "docsrs"]' --no-deps -Zrustdoc-map

Also updating a bunch of dependencies to fix the fallout from rust-lang/rust#138907, though a couple still remain.
