Issue number: N/A

---------

<!-- Please do not submit updates to dependencies unless it fixes an
issue. -->

<!-- Please try to limit your pull request to one type (bugfix, feature,
etc). Submit multiple pull requests if needed. -->

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

When the CI process detects a diff between the output in CI after
running `npm run build` versus the checked out branch, it will log the
diff and exit. It isn't very clear to developers what they need to do or
why this job step exists.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- Logs a prettier error message to the developer to let them know the
steps they can take when a diff is detected in CI
