CI: Update actions and fix warnings (#2435)

* CI: update to checkout@v4 action

Not sure why they decided to bump a major version. It seems like this is
unnecessary churn: actions/checkout#1436 (comment)

* CI: replace archived `actions-rs/toolchain`

It's been unmaintained for four years and has been throwing warnings in
CI:

> The `set-output` command is deprecated and will be disabled soon.

* CI: Bump `cargo-install` action.

This should fix the remaining warnings in CI?

* CI: mdbook-linkcheck: workaround for build error
