The Windows CI checks where the default Bash shell is replaced by Cygwin's are failing with a line 9: syntax error near unexpected token $'\r'' error. This issue is unrelated to this PR, and I'm puzzled as to why it's happening, especially since the .gitattributes file specifies that all text files should be checked out with LF line endings. On the main branch, these checks seem to pass due to a cache hit, which does not occur for pull requests.

I'm unsure whether I should attempt to address this failure within this PR. Overall, testing such a specific Bash shell override with Cygwin feels, in the context of this action, very odd, as I see few practical scenarios where someone would want to override GITHUB_PATH to use it. People using custom runners with such a shell configuration will likely realize that the issue is with their environment and resolve it themselves (it's very likely that other similar actions won't work anyway). I tried tweaking gitattributes in the force-pushes I did to no avail.

Please let me know your thoughts on how to proceed with this PR!
