Bump Spring Boot baseline from 3.2 to 3.3 (#110)

## Change

- Update Spring Boot baseline to 3.3.8 because 3.2.x reached EOL
(2024-11-23). See: https://spring.io/projects/spring-boot#support
- Use Spring Boot Dependencies BOM in parent pom.xml and simplified
dependency management and versioning.
- Configured main pipeline to run tests on Java 23 as well.
- Fix Voyage autotests when API key is not configured.

## General checklist
- [X] There are no breaking changes
- [ ] I have added unit and/or integration tests for my change
- [ ] The tests cover both positive and negative cases
- [X] I have manually run all the unit and integration tests in the
module I have added/changed, and they are all green
- [ ] I have added/updated the
[documentation](https://github.com/langchain4j/langchain4j/tree/main/docs/docs)
- [ ] I have added an example in the [examples
repo](https://github.com/langchain4j/langchain4j-examples) (only for
"big" features)
