The changes released in version 1.4.0 throw an error on mac os runners.

Hi, thanks for reporting the issue and sorry for breaking your CI. Right now I think that could be because of an ancient version of bash on the macOS images. Unfortunately, I don't have any macOS knowledge. I think using brew I can change the bash version.

[GeorgeHahn]

No worries at all! I can look into this sometime in the next week or so if that would be helpful. For the moment, I've pinned the affected project's CI to an older version of the action.

I just pushed v1.4.1 with a fix. I also extended the CI to run on Windows and macOS, such that this problem hopefully doesn't appear anymore. The PR is #10.
