Command not found after the new Beta Version

Hello,

I've encountered an issue after upgrading to the latest beta version of the @antora/collector-extension. Previously, I was able to successfully run commands, including an npm install and custom scripts, using the collector extension. However, after updating to the new beta version, the commands no longer execute and I receive an error indicating that the command is not found.

Expected Behavior: The specified commands, including npm install, should execute without any issues as they did in previous versions.

Actual Behavior: The commands fail to execute, and an error message is displayed: Command not found.

Temporary Workaround: For now, I've reverted to the older Alpha version of the @antora/collector-extension to ensure my builds continue to work.

Question: Should anything be changed in the way commands are configured and run within the antora.yml or other configuration files to align with the new beta version? If so, could you please provide guidance or examples on the updated configuration?
