Unix formatter missing from latest versions of eslint #154
Description
Within the changes to eslint v9, most of the formatters were removed (source) including the unix formatter used by this project. It's been moved to a standalone package. I was confused why eslint.lintProject wasn't returning any errors until I put this together.
May I suggest updating the documentation to mention this? The fix is as simple as npm i -D eslint-formatter-unix.
