BUG: Pwsh (PowerShell 7.x) won't run any commands (Shell plugin)

### Checks

- [x] I have checked that this issue has not already been reported.

- [x] I am using the latest version of Flow Launcher.

- [ ] I am using the prerelease version of Flow Launcher.

### Problem Description

I tried with basic commands like checking PowerShell versions or pinging 8.8.8.8. It works in CMD and PowerShell (as in Windows PowerShell, the blue icon one). But in Pwsh (the black icon one), the window always appear for a split second before disappearing.

### To Reproduce

1. Open Flow Launcher Settings
2. Go to Plugin > Shell > tick "Do not close Command Prompt after command execution"
3. Choose Pwsh
4. Open Flow Launcher
5. Type the action keyword (in this case `>`), then the command you want to run (e.g `ping 8.8.8.8`, `$PSVersionTable`)
6. PowerShell window will always appear for a split sec before immediately disappearing
