Incorrectly logging git-linguist errors

Our GitLab 14.4.2 instance is logging lots of these errors:

Since the log message indicates "command.exitCode":0, I suspect the command is actually succeeding and is only logging the error because of this output to stderr: PID 33555 BUNDLE_GEMFILE=/srv/gitaly-ruby/Gemfile\n.

A potential fix I tried was to comment out this line in my ruby-cd file, and it did clean up the logs.
