Summary

An out-of-date Cargo.lock is the source of rebase conflicts, prevents a
reproductible build, introduces desync between the series that introduces a
change in dependencies and the one that eventually commits the Cargo.lock,
and is just a general annoyance.

This commit demonstrates that the test works, the next one fixes the
currently out-of-date Cargo.lock.

Check if Cargo.lock is up-to-date. Will fail with a 101 error code if not.
$ cargo check --locked --all --quiet
However most CIs will run `cargo build` or similar before running the tests, so we need to check if it was modified
