Proposed fix for issue 5593 (#5597)

Possible fix for #5593

Android 14 requires `RECEIVER_EXPORTED` or `RECEIVER_NOT_EXPORTED` flag
when using `registerReceiver` command:

Currently, `com.google.firebase:firebase-ml-modeldownloader:24.2.1` uses
the `registerReceiver` without this flag:

https://github.com/firebase/firebase-android-sdk/blob/ac19e5d561d6a7a24a6004746d95f4e08024fdc4/firebase-ml-modeldownloader/src/main/java/com/google/firebase/ml/modeldownloader/internal/ModelFileDownloadService.java#L214-L215

Proposed fix:
```java
context.registerReceiver(
          broadcastReceiver,
          new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE),
          context.RECEIVER_NOT_EXPORTED);
```


An alternative solution is using ContextCompat but requires version
1.9.0 of `androidx.core:core`. I noticed in the [Android
documentation](https://developer.android.com/guide/components/broadcasts#java)
is using `ContextCompat` for calling `registerReceiver`, or for the flag
`RECEIVER_EXPORTED` & `RECEIVER_NOT_EXPORTED`:
```java
ContextCompat.registerReceiver(
          context,
          broadcastReceiver,
          new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE),
          ContextCompat.RECEIVER_NOT_EXPORTED);
```

However, `ContextCompat.RECEIVER_NOT_EXPORTED` and the
`RECEIVER_NOT_EXPORTED` from `context` have the same value, so I don't
think this is necessary to use ContextCompat.

FYI, added `@SuppressLint("WrongConstant")` annotation due to the method
throwing an error: https://stackoverflow.com/a/74433641
