Issue:
[Bug] "Include apps from windows store" does not work
Application Search is still broken for me on 9.4.0. This could potentially be related to #1124 and/or #1030.

Steps to reproduce the behavior:
1. Open Ueli (via the global keyboard shortcut or right click on tray icon -> Show)
2. Try to search for any installed application
3. Notice that no applications show up


Debug logs:
I noticed the following debug log message appears every time the scanner re-searches for applications:

```
ERROR] Failed to get search result items for extension with id 'ApplicationSearch.Reason: RangeError [ERR_CHILD_PROCESS_STDIO_MAXBUFFER]: stdout maxBuffer length exceeded'
```

Environment:
 - OS: Windows 11
 - Version 9.4.0

Notes:
Sometimes playing around with the settings under the _Search Engine_ section, some of the installed applications start to show, but not all of them, and not all the time.


Pull request:
refactor(CommandlineUtility): added `maxBuffer` option
This PR adds a parameter `maxBuffer` when executing cli programs.

Might fix #1189
