chore: upgrade to Spring Boot 3.2.2, Kotlin 1.9.22

This upgrade includes
some changes of the test codes
which corresponds to significant changes
that have been made in Spring Boot 3.2.

mybatis project encountered the same issue,
so its pr helped a lot making this upgrade done.
The brief explanations are:

1. As of Spring Framework 6.1, we can't pass the value of `factoryBeanObjectType` as `String` to `BeanDefinition`.
2. `BeanFactory.getBean()` in `BeanFactoryExtensions` has been changed.

Good thing is, the changes above
don't seem to affact the implementations.
All we need to do is to correct the test code.

For the details, please check the references below.
