#241 Update dependency Spring to version 6.x

- sets the compiler level to `17` to comply with Spring 6.x requirements
- updates Spring dependencies to version 6.0.13
- adds necessary references to `spring-context` in wikimachine pom.xml
- removes reference to `XmlBeanFactory` in `SpringFactory` as this interface was long-time deprecated and removed in Spring 6.x
