PowerShell 5.1, used on some Windows GitHub Actions runners, requires
Expand-Archive to receive a file with a .zip extension. The @actions/tool-cache
downloadTool function saves to a temp path without any extension, causing
extraction to fail on PS 5.1. Rename the file to add .zip before calling
extractZip.
