Snap: /snap/freecad/2266/usr/bin/openscad: error while loading shared libraries: libQt5Multimedia.so.5: cannot open shared object file: No such file or directory

### Problem description

I selected OpenSCAD in the Toolbox dropdown, entered some OpenSCAD code, e.g.

cube([1,2,3]);

and clicked "Refresh", which resulted in this error:

/snap/freecad/2266/usr/bin/openscad: error while loading shared libraries: libQt5Multimedia.so.5: cannot open shared object file: No such file or directory

### Workbench affected?

Other (specify in description)

### Steps to reproduce

I can't upload a zip file, it just says "failed to upload zip".

Anyway, to reproduce:

1. Choose OpenSCAD from the toolbox dropdown
2. Click the "Add OpenSCAD Element" button
3. Enter some valid OpenSCAD code, e.g. cube([1,2,3]);
4. Click Refresh button
5. Error occurs: /snap/freecad/2266/usr/bin/openscad: error while loading shared libraries: libQt5Multimedia.so.5: cannot open shared object file: No such file or directory

### Expected behavior

I didn't expect an error - I expected the code to work.

### Actual behavior

I get this error:

/snap/freecad/2266/usr/bin/openscad: error while loading shared libraries: libQt5Multimedia.so.5: cannot open shared object file: No such file or directory

### Development version About Info (in Safe Mode)

```shell
The OpenSCAD module seems to be missing from the latest weekly release.
```

### Last known good version (optional)

```shell

```

Reproduce the OpenSCAD toolbox flow on Ubuntu Core 24 with Snap 2266, starting from the OpenSCAD workbench integration and the Snap packaging configuration. Check how the bundled openscad executable resolves Qt multimedia libraries. Done means entering valid OpenSCAD code and clicking Refresh no longer reports a missing libQt5Multimedia.so.5.
