Windows aren't being moved to external monitors in Workspaces when launched due to changing screen numbers

### Microsoft PowerToys version

0.99.1

### Installation method

Microsoft Store

### Area(s) with issue?

Workspaces

### Steps to reproduce

I have a laptop, dock and two external monitors. I dock and undock my laptop regularly as I come and go from meetings. Each time I dock, the "screen number" changes in Workspaces for my external monitors. The laptop screen is always 1. When I launch a workspace, only the windows that are to be moved to the laptop screen are moved, as the numbers in my workspace settings don't correlate to the screen numbers of the monitors.

I realised this by recapturing the workspace each time it didn't open correctly, and in the settings, the screen number had increased.

### ✔️ Expected Behavior

The windows to move to the correct monitors when the workspace is launched.

### ❌ Actual Behavior

Only the windows that are located on the laptop screen are moved correctly. The windows that are supposed to be moved onto the external monitors are minimised.

### Other Software

_No response_

Start by reproducing the Workspaces behavior with a laptop, dock, and two external monitors, docking and undocking before launching a saved workspace. Compare the configured monitor numbers with the current screen assignments and use the provided bug report for additional context. Done means workspace windows move to the correct external monitors instead of being minimized.
