Jim Schubert 8766531c56 [java] Fix java version defaulting (#4520)
* [java] Improve assumptions about artifactVersion

The logic to apply a default artifactVersion was faulty, resulting in
generation without an explicit version specified either on the OpenAPI
Document or at the CLI/plugin level would result in poms generated with

    <version></version>

As an example, in any commit made up to 5 weeks before this commit, run:

    ./bin/java-pkmst-petstore-server.sh

The solution is to ensure that artifactVersion isn't overwritten by an
"in-process" additonalProperties map, and also to ensure that
additionalProperties is synced with the artifactVersion property once it
has been modified.

As a future task, we'll want to move any modification of
additionalProperties outside of preprocessOpenAPI (to processOpts).
We're hiding manipulation of the "Opts" at a point where we should
really only be applying logic on top of the OpenAPI doc.
