Code Review

This pull request updates several dependencies in dataproc/package.json, including @google-cloud/dataproc, @google-cloud/storage, c8, and chai. The review feedback correctly identifies that upgrading chai to ^6.0.0 will break the tests because Chai v5 and above are ESM-only, whereas this project is configured as CommonJS. It is recommended to revert chai to ^4.5.0 to maintain compatibility.
