[JAVA-2306] Moved articles from spring-persistence-simple-2

* https://www.baeldung.com/spring-jdbctemplate-testing went to spring-jdbc

* https://www.baeldung.com/spring-jdbctemplate-in-list went to spring-jdbc

* https://www.baeldung.com/spring-mock-jndi-datasource went to spring-persistence-simple

* Deleted spring-persistence-simple-2 module as all articles have been moved
