Add support for Spring Boot 4.0.0-M3

[salmar]

Spring Boot 4.0.0-M3 now uses Jackson 3. At startup (using springdoc-openapi v3.0.0-M1), when registering the HAL module, it fails with the following exception:

Caused by: java.lang.NoClassDefFoundError: org/springframework/hateoas/mediatype/hal/Jackson2HalModule

The HAL module should be replaced with https://github.com/spring-projects/spring-hateoas/blob/main/src/main/java/org/springframework/hateoas/mediatype/hal/HalJacksonModule.java

also, this issue is still broken in 3.0.0-M1
