Executable model build fails when a global variable is set in RHS

Issue

If a global variable is set in RHS like the following:

rule "setting_GlobalLogger"
    dialect "mvel"
    when
    then
                drools.workingMemory.setGlobal("logger", org.slf4j.LoggerFactory.getLogger(getClass()));
end

executable model build fails with the error:

[ERROR] Failed to execute goal org.kie:kie-maven-plugin:7.67.0.Final-redhat-00017:generateModel (default-generateModel) on project reproducer_setGlobal: Execution default-generateModel of goal org.kie:kie-maven-plugin:7.67.0.Final-redhat-00017:generateModel failed: [com/example/reproducer/P6F/LambdaConsequence6F52E5BBA430E99186E57ACE461419EA.java (25:908) : workingMemory cannot be resolved or is not a field] -> [Help 1]

This does not happen with non-executable model build (i.e mvn build with -DgenerateModel=NO option).
