Warning about non-existing config.xml emitted during browser platform restore

# Bug Report

## Problem

When restoring browser platform with cordova-plugin-device active, the following warning is emitted:
```
config file config.xml requested for changes not found at /path/to/project/platforms/browser/config.xml, ignoring
```

To reproduce, on a freshly created new cordova project:
```
cordova platform add browser
cordova plugin add cordova-plugin-device <-- no warning emitted here
rm -rf platforms plugins
cordova prepare browser <-- warning emitted
```

## Information

### Version information
cordova@11.0.0
cordova-browser@6.0.0
cordova-plugin-device@2.0.3

## Checklist

- [x] I searched for existing GitHub issues
- [x] I updated all Cordova tooling to most recent version
- [x] I included all the necessary information above

Reproduce the warning with the listed `cordova platform add browser`, plugin installation, cleanup, and `cordova prepare browser` sequence, then trace the browser platform restore path that handles the missing `config.xml`. Done means the restore completes without this warning while the platform and plugin setup still works as expected.
