Current Behavior

When running npm/cli tests on windows, I was seeing many files churn in and out of the source control files list.

These ephemeral test files slow down the IDE considerably and can make it hard to see what actually changed.

Expected Behavior

Files created by tap tests should either be:

1. ignored by gitignore.
2. created outside the git working tree

Steps To Reproduce

1. In VSCode on Windows, clone https://github.com/npm/cli
2. Open the Source Control pane
3. Run npm test

Environment

• npm: 9.6.7
• Node: 18.17.1
• OS: Windows 11
• platform: AMD64 Desktop
