Prevent Cargo.lock for datafusion-cli being out-of-date

[isidentical]

Is your feature request related to a problem or challenge? Please describe what you are trying to do.
Since the only Cargo.lock that is checked in is the datafusion-cli's one, we seem to be forgetting about updating it sometimes.

Describe the solution you'd like
Since we already have infrastructure (a lint job), I think it should be relatively simple to add a step that checks whether the Cargo.lock is up-to-date or not. It could then fail on PRs that change Cargo.toml (add new stuff to other crates), and let the PR authors know that they need to update the lock as well.

Describe alternatives you've considered
Leaving as is.
