Subject: [PATCH] test: update test-child-process-windows-hide to use node:test

This commit updates test/parallel/test-child-process-windows-hide.js
to use node:test. This allows the test to use the built in mocking
functionality instead of managing spies manually. It also prevents
multiple child processes from being spawned in parallel, which can
be problematic in the CI.
