ce activate fails when run detached from terminal

[aleun]

This is a blocking bug for CI scenarios because this is how ce activate would run as part of a GH workflow or ADO pipeline.

From powershell.exe on Windows

Steps:

1. iex (iwr -useb aka.ms/install-ce.ps1)
2. ce --accept-eula
3. ce activate 2>&1 | write-host <-- redirect to detach streams from terminal

Expected: ce activation succeeds

Actual:

vcpkg-ce command line utility [0.4.169]
