[LOG4J2-1885]: Fix docs about additivity


> documentation error regarding additivity default value
> ------------------------------------------------------
>
>                 Key: LOG4J2-1885
>                 URL: https://issues.apache.org/jira/browse/LOG4J2-1885
>             Project: Log4j 2
>          Issue Type: Bug
>          Components: Documentation
>    Affects Versions: 2.8.2
>            Reporter: Hal Deadman
>            Assignee: Matt Sicker
>              Labels: documentation

> On this page: https://logging.apache.org/log4j/2.x/manual/configuration.html
> There is the following sentence:
> "The additivity attribute may be assigned a value of true or false. If the 
> attribute is omitted the default value of false will be used."
> Additivity controls the inheritance of appenders from parent loggers, 
> correct? There are examples in the documentation that say will you will get 
> duplicate logging if you don't set additivity to false (if you are setting 
> the same appender at the root and on the logger). That implies that the 
> default additivity is true, which would be consistent with logback, log4j, 
> etc.
