`rtMavenRun` fails with Maven 3.9.2 because `dependenciesValidators` is `null`

[kiwi-oss]

Describe the bug We use the Maven Wrapper and rtMavenRun to execute our builds on Jenkins. It works fine with Maven 3.9.1, but with 3.9.2, it fails consistently in all projects with the message that dependenciesValidators is null. Here's one example of a call and corresponding log:

rtMavenRun(
    goals: 'versions:set --define newVersion=1.1.30-PR-19-20230614192843-SNAPSHOT',
    resolverId: 'MVN_RESOLVER',
    deployerId: 'MVN_DEPLOYER',
    pom: 'pom.xml',
    useWrapper: true
)

WARNING org.apache.maven.plugin.internal.DefaultPluginValidationManager - 
ERROR org.apache.maven.cli.MavenCli - Cannot invoke "java.util.List.iterator()" because "this.dependenciesValidators" is null

Running with --define maven.plugin.validation=VERBOSE didn't provide any information that seems useful, just some warnings about possible issues with Maven 4.

It fails no matter if the job is run on a GCP agent or on the Jenkins controller. The only difference is that on the controller, the final error message is just "NullPointerException".

When running the same execution locally via mvnw, the build succeeds. There, one more plugin with validation issues is reported:

[WARNING] Plugin validation issues were detected in 4 plugin(s)

[WARNING]  * org.codehaus.mojo:versions-maven-plugin:2.15.0
[WARNING]  * org.sonarsource.scanner.maven:sonar-maven-plugin:3.9.1.2184

To Reproduce Create a project with the Maven Wrapper configured to use Maven 3.9.2 and execute any goal, e.g. package, via rtMavenRun in the Jenkinsfile.

Expected behavior The build should pass like it did with Maven 3.9.1 and like it does with 3.9.2 locally.
