Describe the bug
When using built-in staged-lint with Biome it fails on ESLint configuration missing:
johndoe@Johns-MacBook-Air project % git commit -S -m "chore: update dependencies"
[ERROR] Command stderr:
Oops! Something went wrong! :(
ESLint: 9.39.1
ESLint couldn't find an eslint.config.(js|mjs|cjs) file.
From ESLint v9.0.0, the default configuration file is now eslint.config.js.
If you are using a .eslintrc.* file, please follow the migration guide
to update your configuration file to the new format:
https://eslint.org/docs/latest/use/configure/migration-guide
If you still have problems after following the migration guide, please stop by
https://eslint.org/chat/help to chat with the team.
