Add apm-agent-plugin support for vertx 5.x

## Is your feature request related to a problem?
no. vert.x 5 was released in may 2025 and is considered the current stable version which appears not to be supported currently.

## Describe the solution you'd like
I'd like to see a apm-vertx5-plugin

## Describe alternatives you've considered
Currently we disable instrumentation for our vertx 5 projects with `-Delastic.apm.disable_instrumentations=vertx`
