New issue by PaperMountainStudio on void-packages repository

https://github.com/void-linux/void-packages/issues/24964

Description:
<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->
### System

* xuname:  
 `Void 5.8.9_1 x86_64 GenuineIntel uptodate hold rrrmDDDDDDDDDFFFFFFFFFFFFFFFFFFFF`
* package:  
  ``gtk+3-3.24.22_1`` and ``gtk4-3.94.0_2``

### Expected behavior
When programs use GTK's FileChooser, Filechooser actually appears and the program does not crash.

### Actual behavior
When gtk4 was installed after gtk3, FileChooser doesn't appear and the program crashes.

### Steps to reproduce the behavior
First, install gtk3
```
%: sudo xbps-install -S gtk+3
```
Then gtk4:
```
%: sudo xbps-install -S gtk4
```
Make a program use filechooser. The fastest way is probably glade which uses filechooser immediately on start.
```
%: glade
(glade:17084): GLib-GIO-ERROR **: 12:38:58.746: Settings schema 'org.gtk.Settings.FileChooser' is not installed
```

The conflicting file is `/usr/share/glib-2.0/schemas/org.gtk.Settings.FileChooser.gschema.xml`

This can be solved by reinstalling gtk+3.
