Tool-Cache: .tar.gz tests fail on Windows

Describe the bug
On Windows the tests for the tool-cache package currently don't all pass. The .tar.gz tests fail with an error saying tar wasn't found.

To Reproduce
On a Windows machine:

1. Clone actions/toolkit
2. On main branch, run the following commands:

   npm i
   npm run bootstrap
   npm run build
   npm run test -- packages/tool-cache
   

Expected behavior
All tests pass on Windows

Actual behavior

Desktop:

• OS: Windows

Run the listed bootstrap, build, and package test commands on Windows, then start with packages/tool-cache/tests/tool-cache.test.ts and the failure at packages/io/src/io.ts:190. Trace the .tar.gz and .tar.xz extraction path and verify that all three failing archive tests pass on Windows without the missing-tar error.
