[sdk-platform-java] Generate native image reflect-config.json for com.google.firestore.bundle

We generate [configurations for `com.google.firestore.v1` classes ](https://github.com/googleapis/java-firestore/blob/main/google-cloud-firestore/src/main/resources/META-INF/native-image/com.google.cloud.firestore.v1/reflect-config.json)but not `com.google.firestore.bundle` classes. These needed to be manually added in https://github.com/googleapis/java-firestore/pull/1419.
