I try to have `jekyll build` fail on errors _without_ all the traceback output, and only have the actual error shown.

Here is a build that fails because [jekyll-scholar](https://github.com/inukshuk/jekyll-scholar) is unable to build a bibliography due to invalid BibTeX.

This is the command: `bundle exec jekyll build --quiet` and here is the error:

Here the same with trace: `bundle exec jekyll build --trace` and the error looks like this:

It seems like neither `--quiet` nor `--trace` actually make a difference, except that the “please add --trace” note is missing.

I would like the entire stack trace to be excluded from the output and only have the actual error message shown. How can I do that? This is using Jekyll 4.2
