[Bug]: xml resources not merged into AndroidManifest

### Capacitor Version

capacitor 7.0.2

### Other API Details

```Shell

```

### Platforms Affected

- [ ] iOS
- [x] Android
- [ ] Web

### Current Behavior

I'm crafting a plugin to use android auto with my app.
To be able to use my app on AA it needed to have this in androidmanifest.xml:
```

```

then the linked file in /android/src/main/res/xml/automotive_app_desc.xml

```

```

After the merge in androidmanifest i have:

```

```
and no automotive_app_desc.xml in any location of the project.

To be able to build for android auto I have to manually add after npx cap sync the file in:
/android/src/main/automotive_app_desc.xml

It would be nice to have it auto merged.

### Expected Behavior

Merged automatically. in AndroidManifest.xml and related files
