Multiple Quake Windows can be opened

### Windows Terminal version

1.16.10261.0

### Windows build number

22000.1696

### Other Software

_No response_

### Steps to reproduce

- Open a WT Instance and enter `wt -w _quake`
- With the quake window open, enter the shortcut keys for opening/closing a quake window (In my case, Win + \`)

### Expected Behavior

The already open quake window should minimize as is normal while using the quake shortcut.

### Actual Behavior

A different quake window opens either above the current quake window or on the currently active screen (if using multiple screens).

Start by reproducing the issue with `wt -w _quake`, then use the quake shortcut while the window is open, including on a multi-screen setup. Trace the existing handling for the `_quake` window target and shortcut action. Done means the open quake window minimizes instead of creating another quake window.
