OpenAPITools generators generate project with dependency on junit

[barchetta]

Testing with latest generators (as of Tim's commit 3e0dad4ce3f17511660a59b5f0a0ce61373de275).

When using the client generators, either MP or SE, the generated project pom.xml has a dependency on junit:

        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <scope>test</scope>
        </dependency>

Generators with the issue:

• [ ] Client MP
• [ ] Client SE

Server generators look to be OK as they depend on junit-jupiter-api which Helidon does manage the version of.

To reproduce:

openapi-generator-cli generate -g java-helidon-client --library mp -i ../../quickstart-openapi.yaml  --additional-properties "helidonVersion=2.5.3"

mvn clean install
. . .
[ERROR] [ERROR] Some problems were encountered while processing the POMs:
[ERROR] 'dependencies.dependency.version' for junit:junit:jar is missing. @ line 49, column 21

I assume an spec.yaml will suffice for reproducing.

Note that this problem was masked with the SE Client when using 3.0.1 because the OCI SDK BOM was managing the junit version:

      <dependency>
        <groupId>junit</groupId>  <!-- com.oracle.oci.sdk:oci-java-sdk:2.37.0, line 566 -->
        <artifactId>junit</artifactId>  <!-- com.oracle.oci.sdk:oci-java-sdk:2.37.0, line 567 -->
        <version>4.13.2</version>  <!-- com.oracle.oci.sdk:oci-java-sdk:2.37.0, line 568 -->
      </dependency>
