Ensure `deprecated` operations are annotated/documented as such on the
generated methods. Libraries updated:
* [feign]
* [google-api-client]
* [microprofile]
* [okhttp-gson]
* [resttemplate]
* [retrofit]
* [retrofit/play*]
* [webclient]
* [vertx]
Ensure `deprecated` schemas are annotated/documented as such on the
generated classes/fields. Libraries updated:
* [feign]
* [google-api-client]
* [jersey2]
* [microprofile]
* [native]
* [okhttp-gson]
* [rest-assured]
* [resteasy]
* [resttemplate]
* [retrofit*]
* [webclient]
* [vertx]
Also fix two minor bugs to get the java sample tests working:
* Fix an invalid jackson-datatype-threetenbp version number in vertx/pom.mustache
* Fix a bad return type in webclient/api_test.mustache when uniqueItems=true
Since this commit updates petstore-with-fake-endpoints-models-for-testing.yaml,
several other samples were updated, but it's just new files to reflect the
deprecated schemas, so there should be no consequential differences.
Relevant bits of the spec:

* https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.0.2.md#user-content-schemadeprecated
