Add execa mock to fix timeout on Node.js 20

The UI prompt tests were timing out on Node.js 20 because they were
missing a mock for the execa call to get the registry URL. This caused
the tests to hang when trying to execute `npm config get registry`.

Added execa mock to both version.js and tags.js tests to return a
fake registry URL, which prevents the actual command execution and
makes the tests run much faster (600-900ms instead of 4-8s).
