[JAVA][KOTLIN][SPRING] upgrade dependencies (#16759)

* upgrade spring-boot-starter-parent

* upgrade springdoc and swagger-ui

* upgrade v3 swagger-annotations

* generate samples

* upgrade jackson

* fix spring cloud, remove temp comment

Putting "8" instead of "1.8" should be ok, because Spring Boot 3 requires Java 17 anyway, so it should be able to understand that 8 is the same as 1.8.

* generate samples

* upgrade JUnit 5, remove commons-io dependency, remove outdated samples/client/petstore/java/feign/feign10x/ files, generate samples

commons-io dependency was introduced in https://github.com/OpenAPITools/openapi-generator/pull/8484, but I don't see why it would be needed now or back then.

* update gson, generate samples

* update logback

* update feign

* update scribejava

* generate samples

* update httpmime

* okhttp-gson: update commons-lang & okhttp & junit-platform, remove mockito; generate samples

It seems Mockito is not used at all there.

* okhttp-gson: remove unnecessary sample files, generate sample files

* upgrade google-api-client & jersey-common, restore ClientTest, generate samples

* misc. upgrades in jersey2 and jersey3

jersey 3.1.3 is available already, but IntelliJ reports security problems in 3.1.3 and 3.1.2, so I used 3.1.1 instead.

* align some gradle&sbt files with poms, generate samples

* whitespace fix
