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* upgrade JUnit 5, remove commons-io dependency, remove outdated samples/client/petstore/java/feign/feign10x/ files, generate samples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

It seems Mockito is not used at all there.

* 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
* fix: Using Map.Entry to avoid "reference to Entry is ambiguous"
when spec defines a model Entry it conflicts. Also rest of mustache
uses Map.Entry to matching it
* fix: Map.Entry - update samples
* Support for multipart/form-data; charset="utf-8"
Previously, it was only checked for an exact equal string, which failed when there were additional options such as charset.
* Update samples
