Is your feature request related to a problem? Please describe.

Java vertx uses a library which is not maintained anymore since 2 years https://github.com/phiz71/vertx-swagger and doesn't work with recent Vert.x. This template should be marked as deprecated and java-vertx-web (the one updated to latest Vert.x) should be suggested instead in the generators list: https://openapi-generator.tech/docs/generators/

Describe the solution you'd like

Mark as deprecated the old java-vertx template
