Respect spring.dao.exceptiontranslation setting

Update `DataSourceTransactionManagerAutoConfiguration` to respect
the `spring.dao.exceptiontranslation` setting. If `exceptiontranslation`
is `false` then we create a classic `DataSourceTransactionManager`
rather than a `JdbcTransactionManager`.

Fixes gh-24321
