If a Biomefile is empty, Biome can't `use` it.

This issue has no description.

The issue title suggests a problem when Biome tries to `use` an empty Biomefile. Start by looking at the `use` command implementation in the codebase, likely in a shell script file. Examine how the Biomefile is read and parsed. Check for error handling when the file is empty. Run the tool with an empty Biomefile to reproduce the issue and see the error message.
