Tested locally with mypy_primer -k common-workflow-language

This is ready for review and merging, thanks!

I'm not sure grep here is allowed because mypy-primer should (though it's kinda bad at it) be able to run on Windows.

... though tbh I was looking at making mypy-primer run on Windows and ended up having to exclude projects so a only_platform kwarg might work well...

Then cwltool and schema-salad should be excluded from MS Windows anyhow, as they explicitly don't support that platform 😊

So, I'd like the keep the grep.

Thanks, would you mind marking it using the nice supported_platforms annotation A5rocks added in https://github.com/hauntsaninja/mypy_primer/pull/110/files

@hauntsaninja Done, thank you!
