Fix new suppress terminal setting

Behaviorally it was working, but it wasn't showing up in the settings.
We also hadn't mapped it into our (pointless IMHO) `Settings` class,
or put it under the "correct" section of `integratedConsole`.

To be honest, it's open work to migrate away from `getSettings()`
and to just using the VS Code APIs directly, but we shouldn't do it now.
