Windows - Action fails to extract terraform zip

[cpc-camarj]

It appears that GitHub action attempts to extract the directory which stores the zip file rather than the zip file itself.

Did some more digging, and this appears to be coming from the @actions/tool-cache dependency.

C:\runner\_work\_temp\6f8260ff-0480-4753-a60e-631c39fe0016 is the actual file and not a directory, as I was assuming. Unless something has changed, I remember that Windows is pretty particular about file endings, so the Expand-Archive command may be failing due to the file not ending in .zip.
