Deprecation Warning for MapperOptions.Builder in Morphia 2.4.4 but as per migration doc it remains undeprecated

[waqarabbas]

Hello Morphia Team,

I am currently using Morphia 2.4.4 and encountering deprecation warnings when using MapperOptions.Builder, despite documentation suggesting it was undeprecated as of version 2.4.

Issue Description: When initializing MapperOptions with the builder pattern, a deprecation and removal warning is displayed. **

Warning 'dev.morphia.mapping.MapperOptions.Builder' is deprecated since version 2.4.0 and marked for removal.

Sample Code

public class SomeClass extends DatastoreImpl {

    private static Datastore initDS(final MongoClient moClient, final String db) {
        MapperOptions options = MapperOptions.builder()
                                             .collectionNaming(NamingStrategy.identity())
                                             .build();

        return Morphia.createDatastore(moClient, db)
                      .configure(options);
    }

    public SomeClass(final Morphia morphia, final MongoClient mongoClient, final String dbName) {
        super(initDS(mongoClient, dbName));
    }

    private void ensureAndPopulateIndexes() {
        // Ensure and populate indexes as necessary
    }

    private void initType(Class<T> entityClass) {
        // Initialize entity type
    }
}
