@JsonTest and @AutoConfigureJson fail when using spring-boot-jackson2

[marcrohlfs]

In org.springframework.boot:spring-boot-jackson2:4.0.0-RC1, the package of the Jackson2AutoConfiguration in the META-INF/spring/org.springframework.boot.test.autoconfigure.json.AutoConfigureJson.imports is wrong. It's
org.springframework.boot.jackson.autoconfigure.Jackson2AutoConfiguration instead of
org.springframework.boot.jackson2.autoconfigure.Jackson2AutoConfiguration. This causes runtime failures when using spring-boot-jackson2.

Thanks for letting us know. I'll get that fixed.

We have a build task that checks the imports files. It should have caused the build to fail in this case. I've opened #47812 to investigate why that didn't happen.

Re-opening as @JsonTest is similarly affected.
