Modal: Setting resource-id from testID prop (#48313)

Summary:
Follow up from #48271 and #48254, I noticed that the Modal component also doesn't map the `resource-id` from the `testID` on Android. This PR addresses that.

## Changelog:

[ANDROID] [FIXED] - Modal: Setting `resource-id` from `testID` prop

Pull Request resolved: #48313

Test Plan:
Alternatively do:
```
$ adb shell uiautomator dump
UI hierchary dumped to: /sdcard/window_dump.xml
$ adb pull /sdcard/window_dump.xml
/sdcard/window_dump.xml: 1 file pulled, 0 skipped. 1.1 MB/s (3505 bytes in 0.003s)
```
and check in XML: ` resource-id="playground-modal"  class="android.view.ViewGroup" `
-------
Using Appium, check that the `testID` prop passed from JS is mapped as `resource-id` in the rendered view group of the Modal.

<summary>Example of the code implementation in the RNTester Playground:</summary>

```tsx
function Playground() {
  const [modalVisible, setModalVisible] = React.useState(false);

  return (
    <>
      <Modal
        visible={modalVisible}
        testID="playground-modal">
        <Text testID="inner-text-test-id">Hello World!</Text>
      </Modal>

      <Button
        title="Open Modal"
        onPress={() => {
          setModalVisible(true);
        }}
      />
    </>
  );
}
```
