MacOS issue: brew install needs linux?

`brew install codeGROOVE-dev/homebrew-tap/review-GOOSE` (btw the readme says incorrectly `codeGROOVE-dev/homebrew-tap/reviewGOOSE` without the dash)

```
...
==> Would install 1 formula:
review-goose
review-goose: Linux is required for this software.
Error: An unsatisfied requirement failed this build.
