Replace BatchJdbcOperations with standard NamedParameterJdbcOperations
BatchJdbcOperations is still there, but deprecated, and not used except for deprecated places kept for backward compatibility. This is possible since Spring Framework made the features offered by `BatchJdbcOperations` part of `NamedParameterJdbcOperations`. See spring-projects/spring-framework#28132 See #1191
